| Abstract: | Although phased-array (PA) radar can suppress sidelobe interference signals due to its directional beamforming capability, it cannot effectively suppress mainlobe interference signals located near the desired target. To address this limitation, we leverage the range-angle dependence of frequency diverse array (FDA) radar to mitigate close-range mainlobe interference. Unlike traditional adaptive beamforming methods, the proposed approach exploits the phase difference between interference and target signals induced by the frequency offset of FDA radar, enabling direct suppression of unwanted signals. The effectiveness of this method is validated through theoretical analysis and numerical simulations. [ABSTRACT FROM AUTHOR] |
