“…In order to construct the hybrid beamforming by taking into account partial CSI, a row‐successive‐decomposition (RSD) algorithm and a row‐by‐row (RBR) approach were presented. Kadam et al 33 proposed a novel hybrid beamforming approach called “Dimension Reduced Baseband Piecewise Successive Approximation” in hybrid beamforming for the dual‐functioning MIMO radar system. The spectral efficiency increased by 19%, the bit error rate dropped by 17.5%, and the energy efficiency performance increased by 18%.…”

SummaryThe advanced wireless communication system requires abridged energy consumption, enhanced data rate, and good signal coverage. The massive MIMO technology for 5G systems has been developed to accommodate several users simultaneously with superior throughput. The claim for high data rate wireless communication services is expanding quickly as time goes. Thus, the key difficulty is that as the number of users grows, the number of phase shifters grows as well, causing the system to consume more power; as a result, the system's energy efficiency decreases. Hybrid beamforming has recently emerged as an attractive technique for millimeter‐wave (mmWave) communication systems. The analog beamformer in the RF domain and digital beamformer in the baseband are coupled through a minimal number of RF chains in hybrid beamforming architecture. Hybrid beamforming utilizes fewer RF (radio frequency) chains than the total number of antennas to have a lower energy consumption design. The hybrid beamforming for a mmWave‐based massive MIMO system through different phase shifter selection mechanisms is proposed to achieve the highest energy efficiency for mmWave communications systems. The fully connected with phase shifter selection, sub‐connected with phase shifter selection (SPSS), and fully connected and sub‐connected with phase shifter selection with halved and doubled switches are considered for this research. The simulation results show the SPSS with halved switch outperforms on energy efficiency.

“…There exist several issues while operating with high frequencies and huge bandwidth accessible at mmwave, but the potential of providing high resolution and improved collision detection and avoidance are the points of motivation in dual functioning MIMO radar applications. While scanning, the base station faces difficulty to isolate the side lobes, because the radar beam pattern can shift arbitrarily as the target moves and may obstruct the communication functioning [27][28][29]. Hence to cancel mutual interference, stronger approaches like hybrid precoding design are needed.…”

Inflated communication traffic and expanding radar applications result in frequency congestion and require extra spectrum resources. Dual-functioning multi input multi output radar benefits both sensing and communication operations via real-time cooperation. This decongests the radio frequency environment and allows a single hardware platform for both functionalities. Analog beamforming fails to provide multiplexing gain and digital beamforming is not preferred practically because of heavy power consumption. A reliable hybrid beamforming design is an inherent requirement due to the concerns related to limited RF chains, interference and the cost of fully-digital beamforming. In this paper, Enhanced-Social Ski Driver's algorithm is presented to investigate the performance of hybrid beamforming in dual-functioning MIMO radar. This study investigates location-based direction sensing for Rayleigh and Rician fading channels. This amendment provides improved performance with a minimal bit error rate, maximum gain, and significant normalized array power distribution. The simulation results show 24% reduction in bit error rate, 15% improvement in gain and persistent array power than existing social ski driver's algorithm.

“…Multi-static radars is primarily formed of phased antenna arrays [20][21][22][23] and spacing between them is estimated in wavelength [24]. This method works well for small-scale deployments at large frequencies, requiring small antennas [19,25,26]. However, for large-scale deployments, such as satellite radar platforms, it is difficult to determine the wavelength spacing [27].…”

This article proposes a new engineering approach to detect targets using multi-static radars. It considers the aperture angle and the probability of false alarm of detection which allow to improve the performances of the radar system deployment. This proposed method is tested on three tomographic modes of multi-static radars: Single Input Multiple Output (SIMO), Multiple Input Multiple Output (MIMO), and Synthetic Aperture Radar (SAR). In this work, a calculation and estimation method for the parameters (spacing sensor and tilt angle of baseline) are developed using the deployment of the radar system based on geometrical arrangements. Employing these parameters, estimated by the proposed approach, and using them for the calculation of the tomographic resolution, the nearest ambiguity location, and the scan loss which are radar deployment performances. The results show that the spacing between sensors varies from 40 to 70% with an increment of aperture angle from 15° to 30° and the step of 10 −3 variation in the false alarm probability of detection. The length of the radar system deployment is also reduced by 6.66%. This approach improves the capabilities of distinction of the targets in a multistatic radar system and allows a reduction in deployment costs.
