Optimal Design of OFDM Radar Low Sidelobe Waveform Based on Genetic Algorithm

Radar system environment is complex, and excessively high range sidelobes will cause weak targets to be lost and false targets. To solve this problem, a novel orthogonal frequency-division multiplexing(OFDM) radar low sidelobe waveform design method based on genetic algorithm(GA) is proposed. First,...
