Study on signal processing of azimuth multi-channel spaceborne sar with yaw steering

The signal processing of azimuth multi-channel spaceborne SAR is studied. A compensating method for different path signal error in azimuth is given. A novel method to process nonuniform sampling in azimuth with yaw steering and reconstruction of digital spectrum is proposed. The yaw steering error boundaries are analyzed. All the computer simulation results are presented in detail.
