Trends- 

The past two decades have seen great progress in the development of information and communication technology (ICT), especially for business use. On the other hand, the pace of radar and related technological development remained slow, mainly due to their highly specialized applications and the high costs involved in the hardware and infrastructure associated with these systems. Of late, the situation has changed dramatically, as many ICT applications have made inroads into radar systems. Advances in nanotechnology and semiconductors have also contributed to the miniaturization and diverse applications of radar. Most radar applications have dual use in nature. Any radar designed for surveillance, navigation, and landing can also be used for early warning, battlefield weather forecasting, mission planning, and recovery of military aircraft. New radar technology has equally revolutionized unique military applications such as tracking, fire control, and identification of friend and for (IFF). 

The basic radar range equation in its new incarnations continues to inspire new designs and innovations in commercial and military radars. Important new radar technologies such as multiple inputs, multiple output (MIMO) systems, digital beam forming (DBF) techniques, active electronically steered array (AESA) radars, millimeter-wave radars, passive coherent location radar (PCLR) systems, and semiconductor power amplifiers. PA), intelligent signal coding, and radar digital signal processing (DSP) have inspired many modern radar designs in recent years. 

Some of the Major Technological Trends along with their operational Benefits are: - 

1. Millimeter Wave RADAR: - Millimeter Wave RADAR (mmWave RADAR) is an extremely valuable sensing technology that is ideal for detecting objects and providing information about the range, speed, and angle of these objects. mmWave RADAR technology uses a non-contact system that operates in the spectrum between 30GHz and 300GHz. Millimeter wave radar (mmWave RADAR) has recently attracted significant interest in meeting the capacity needs of future 5G wave networks.
2. Multiple Inputs, Multiple Output Radar (MIMO): - MIMO radar technology evolved from communications systems where it was used to improve coverage area and signal quality. MIMO radars simultaneously radiate uncorrelated signals with orthogonal polarization. This improves coverage and receives signal quality. The decorrelation of a separately transmit signal is crucial for picking up small targets at long distances. A decoupling of about 70 decibels can possibly be achieved with proper modulation. A new generation of Synthetic Aperture Radar (SAR) systems utilize multiple elevations and azimuth receiver channels with digital beam forming (DBF) capability. This allows the synthesis of multiple digital receiver beams for improved signal resolution and reduced noise figures.
3. Broadband Radar and Multifunctional Radio Frequency RF-Systems: - A major trend in radar is the continuous expansion of operational radar frequency ranges toward applications of broadband multifunctional RF systems. An advantage of broadband and wide frequency range applications in radar is that when the available operating frequency range increases, effective jamming, and interference with radar signals becomes more difficult, as jammed frequency bands can be easily avoided and the jamming signal has more RF power. A larger bandwidth is required to be covered with the same RF power density, thus making jamming of broadband radar systems significantly more difficult. Furthermore, increasingly complex operational conditions demand more detailed ultra-high resolution (UHR) Synthetic Aperture Radar (SAR) images of fixed targets for classification support in all-weather, day, and night applications acquired from large stand-off ranges. Such UHR SAR images require very high bandwidth in the range of several GHz, thus supporting the need for broadband multifunctional RF-Systems. The idea of Multifunctional RF-Systems (MFRFS) is that common hardware is used to provide not only radar but also electronic warfare (EW) functionality, such as electronic support (ES) and electronic attack (EA), as well as communication using data. Link functionality. These functions work through a shared AESA antenna. which allows achieving new and unprecedented operational capabilities and uses higher RF output power, higher antenna gain, and higher sensitivity compared to traditional EW antenna systems for ES and EA in use today. These advantages enable early detection and identification, early jamming of adversary targets, higher sensitivity beyond normal ES performance, and thus lower probability of intercept (LPI) operations, and, in general, higher operational flexibility due to the additional spatial degree provided. through such an AESA antenna.However, fully functional MFRFS sensors are not yet available due to the insufficient bandwidth of AESA antennas based on today's conventional semiconductor technology. To meet the bandwidth requirements of an operational EW system, a minimum of C- to Ku-Band bandwidth is required depending on the application concerned. GaN semiconductor technology is the most promising to meet such broadband requirements in combination with sufficiently high RF power and sufficient Power Added Efficiency (PAE) yield.
4. AESA (Active Electronically Scanned Array): - Active electronically scanned array (AESA) technology is gaining traction due to its advanced tracking and detection capabilities. AESA is a controlled array antenna in which a beam of radio waves can be electronically directed in different directions without moving the antenna. New AESA technology has enabled evolution to higher (millimeter wave) frequencies that provide greater resolution with smaller phased array antennas. Compared to conventional mechanically scanned radar systems, these radars have more efficient detection, targeting, tracking, and self-defense capabilities.AESA radar antennas typically have scanning angles less than 120 degrees. For 360-degree coverage, a common solution is to mount them on a mechanically rotating platform. Full 360-degree coverage with a fixed array using back-to-back antenna panels has recently been demonstrated. Raytheon's self-funded prototype is designed as an upgrade to the Patriot missile system. Other systems use multiple panels connected to a single radar system (three or more) to provide Omnidirectional scanning and tracking capabilities, notably, the cost of an AESA system is roughly proportional to the size and performance of the array and the number of TR modules.
5. Passive Coherent Location Radar System: - A passive coherent location radar (PCLR) is an application of bistatic radar. These radars under development use public broadcasting stations (FM radio stations, cellular phone base stations, and digital audio broadcasts) as target illuminators, also called transmitters of opportunity, and are inherently very difficult to detect and jam. PCLRs are highly cost-effective compared to active radar systems with comparable performance because available transmitters are used free of charge. Individual receivers can be easily replaced for better performance. These radars are likely to find applications in wide area surveillance around airports and other important locations to complement existing radars that use their own transmitters with conventional power amplifiers.
6. Distributed Aperture Radar Systems: - Modularity and scalability of modern radar sensors are progressive trends and a key factor in designing cost-effective sensors such as HENSOLDT's TRS, TRML, Spexer, and PrecISR radar families. These trends also extend beyond single radar operation, through networked operational capabilities and distributed radar aperture systems, to increase the diversity of detection information, reduce time on targets, improve target re-encounter time, and provide better and more complete situational awareness.
7. Reflector-based DBF SAR: - A novel DBF SAR system uses THE reflector antennas. A concept that offers better performance and a lower level of complexity compared to DBF radars using planar antennas. Spaceborne systems based on this concept are currently being studied and have already been discussed in several publications including this one. To demonstrate the performance of the reflector-based DBF radar and to verify the theoretically obtained results, a reflector-based configuration of the demonstrator was constructed. For this, an elliptical antenna of size 1.2 x 0.8 m, a focal length of 0.8 m and offset clearance of 0.6 m in the major axis were selected. The feed system consists of 8 horn antennas that provide optimum illumination on the antenna surface. Its architecture is highly flexible allowing for varying the inter-element spacing in the feed as well as the position of the entire system relative to the antenna. 

Using such a configuration it will be possible to test various operational options of reflector-based DBF SAR including advanced operational modes in bi- and mono-static configuration, inverse DBF SAR, and the use of conjugate field matching principle for antenna optimization. In addition to the patterns, some of the effects found in such systems can also be studied, among others, the effect of the shape of the reflective surface and possible distortions on DBF performance, frequency-dependent effects, and the effect of specific antenna parameters on DBF radar characteristics. 

Some of the latest applications and technological advancements in the radar systems market are: - 

• Semiconductor Power Amplifiers: - Traditional power amplifiers (PA) system design has undergone dramatic changes. The use of Gallium Nitride (GaN) power transistors in PAs has led to a change in design. The power handling capabilities of these new generation semiconductor devices are comparable to earlier traveling wave tubes (TWTs). The main reason is that GaN PA's power handling capacity, reliability, and bandwidth are much higher than other solid-state technologies. They have overcome the reliability, size, and maintenance problems associated with TWTs. GaN PAs are very coarse and offer very high thermal stability. GaN technology is also used for low noise amplifiers (LNA) with the same rugged characteristics as GaN PAs, sensitive receiver technology that is easily jammed, damaged, or affected by limited dynamic range due to low input voltage thresholds. It also offers improved detection ranges considered unattainable due to noise associated with the signal. Techniques such as intelligent signal coding and new generation digital signal processing have also contributed to the better design features of modern radars. 
• Intelligent Signal Coding: - Similar to communication systems, signal coding schemes such as OFDM (Orthogonal Frequency Division Multiplexing), DSSS (Direct Sequence Spread Spectrum), and CDMA (Code Division Multiple Access) are finding applications in new radars. Employing these schemes, increases th compression gain by 50 to 70 decibels and reduces transmitter power requirements. Variations of OFDM carrier modulation such as QAM (Quadrature Amplitude Modulation) and PSK (Phase Shift Keying) can also be used. Identification of these radar signals for localization and countermeasures becomes more difficult for military applications. 
• Radar Digital Signal Processing: - The echo signal input to the receiver changes in amplitude, range, and Doppler. The information content is separated using discriminator or demodulator devices in the form of discriminator, range, and doppler. Range and Doppler can be determined by simple Fourier transforms. A large number of targets can be handled using DSP (Digital Signal Processing) in radar. Using DSP increases the overall efficiency of the radar by about 10 decibels. 
• LIDAR Sensors in Automotive Radars: - Automotive manufacturers are increasing LIDAR (Light Detection and Ranging) sensors in automotive radars to collect data faster with higher accuracy. LIDAR uses pulsed laser light to illuminate a target and reflect the pulses back to the sensor, and the differences in laser return times and wavelengths are used to create a 3D representation of the target. LIDAR mounted on top of vehicles provides a 360-degree view of obstacles that vehicles must avoid. LIDARs in automotive vehicles typically use a wavelength of 905nm which can provide a range of up to 200m under restricted conditions. LIDAR is primarily used in self-driving cars. 
• Integration of Radars and GPS: - Radar manufacturers are augmenting GPS with civil radars to improve tracking accuracy in security and navigation systems. The integration of radar and GPS into security systems provides automatic target tracking, friend or for tracking, and observation of areas in the dark. For example, PureTech Systems integrates radar and GPS technology into its automated outdoor surveillance system, PureActiv, which provides security professionals with accurate and reliable surveillance in indoor, outdoor, and remote environments. In the navigation system, radar detection technology and GPS are being integrated to provide drivers with information related to speed limits, red light signals, 3D mapping of surroundings, lane assist, and others. 

• 3D Radar Systems: - Many companies and military organizations globally are investing in 3D radar systems to increase the efficiency and effectiveness of weather monitoring, and military and surveillance systems. In a 3D radar system, all three space coordinates are measured within the radar system. The 3D radar consists of pencil beams that are rotated for scanning purposes. Behind each scanning rotation, the antenna elevation is shifted to the following sound. This process is repeated at several angles to scan the entire volume of air around the radar at its maximum. 3D radars are now replacing 2D radars mainly in the defense and weather industries. 
• Multifunctional Resource and Sensor Management: - The variety of new possibilities provided by future radar trends must be optimized through flexible and modern radar resource management that allocates resources according to the quality needs of specific radar tasks rather than fixed rules. One of the latest highly advanced real-time enabled service (QoS) based resource management schemes that allow finding globally optimized solutions (according to specific conditions) is a quality-of-service resource allocation method called QRAM. The QRAM method allows optimizing the allocation of resources such as time, RF power, frequency bandwidth, computational power, antenna sub-aperture, RF-channel, etc. to a given radar task, according to specific quality criteria that may also depend on a real mission. Hence by optimized allocation of frequency and bandwidth as well as splitting of time slots between different radar tasks, faster reaction time and less sensor blind time can be achieved. Based on the high availability achieved through optimized inter-coordinated radar functions, the efficiency of the entire radar system will be significantly enhanced. 

Radar's innovative system technology has the potential to lead to many new functions and applications, potentially replacing most existing system concepts. Future radars are likely to be smaller in size and lower in cost but with higher information content. Most of the technologies maturing in the ICT domain are likely to be integrated into future radars. Automobile radars are meanwhile being mass-produced for safe and autonomous driving. The fastest growing market for radar applications is likely to be in automotive systems.
