Transmit-Receive Subarrays for MIMO Radar Array Antenna

Syahfrizal Tahcfulloh

Abstract


The phased multiple-input multiple-output (PMIMO) radar uses subarrays in transmit array that overlap one another to exploit the main advantage of the phased array (PA) radar, i.e., high directional coherent gain, and the main advantage of the MIMO radar, i.e., high waveform diversity gain. This paper has derived the radar formula that utilizes overlapping subarrays on transmit (Tx) and receive (Rx) array simultaneously called the transmit-receive subarrays of MIMO (TRSM) radar. The use of overlapping subarrays in Tx-Rx establishes the TRSM radar has high flexibility to configure the number of Tx-Rx subarrays that use the performance of all the gains simultaneously, so that produce Tx-Rx beampattern and signal-to-noise-plus-interference ratio (SINR) more than those achieved by PMIMO radars. The approach aims to overcome the beam shape loss, increase the transmit-receive gain, minimize the maximum peak sidelobe levels, narrow the half-power beamwidth, increase directivity, and increase SINR. The effectiveness of this radar's performance is compared to the PMIMO radar in various methods such as equal subarrays, unequal subarrays, and optimum partitioning, the PA, and the MIMO radar. The numerical simulation and evaluation results show that the proposed radar has several advantages such as lowest the peak sidelobe level, narrow the half-power beamwidth, and high directivity, so it is very resilient to interferences on target locations. The effect of the number of subarrays as a function of performance parameters on the Tx-Rx array that is ready to adjust to the detected target conditions is also presented.
