Abstract

Formation-Flying Satellite radar system can fundamentally improve radar imaging performance by using a group of specially designed orthogonal waveforms. Based on studying the performance of LFM signal and phase coded signal, we modulate the same LFM signal using different phase coded signals, and generate the orthogonal phase code division multiplex linear frequency modulation (OPCDM-LFM) compound waveforms. The genetic algorithm is introduced to numerically optimize the compound waveforms. The simulation results show that the synthetic performance of the proposed waveforms in range resolution, orthogonal performance, Doppler tolerance and the utilization ratio of bandwidth is very well.
