Abstract :
A multi-channel equalization algorithm combined with spectrum correction is proposed, suitable for SAR/GMTI system with small time-bandwidth chirp signal. The experimental results show the algorithm not only can compensate the channel mismatch, but also obtain satisfied pulse compression performance.
