Abstract :
Multi-channel SAR enables wide swath with high azimuth resolution. Azimuth non-uniform sampling will occur due to the nature of the orbit in the multi-channel SAR. In order to use the frequency imaging algorithm, an inverse-filter method is proposed to obtain the azimuth spectrum of the azimuth non-uniform sampling. Simulation results validate the presented algorithm.
