N2 - Frequency Diverse Array Multiple-Input Multiple-Output (FDA-MIMO) radar employing linear frequency offsets and fixed array element spacing produces periodic beam patterns, which can lead to serious failures in suppressing main lobe interference using beamforming-related algorithms. To address this issue, several different frequency offset and array element spacing settings are used in this study to eliminate the periodicity of the beam pattern, which is then applied to suppress the main lobe interference in the FDAMIMO radar scenario, and finally, its suppression effect is compared with that of the frequency diverse array (FDA) radar. The results show that the use of exponential frequency offset and linear array spacing setting, called expf, provides optimal main lobe interference suppression performance for the FDA-MIMO radar, with an improvement in SINR of 9.94 dB compared to the FDA radar under the same settings.
