Abstract
The azimuth multichannel is incorporated into BS-SAR (spotlight SAR, sliding spotlight SAR or TOPS SAR). The signal reconstruction algorithm used for multichannel stripmap SAR may not be effective for multichannel BS-SAR (MC-BS-SAR). In this paper, a multichannel full-aperture azimuth processing algorithm is proposed for a BS-SAR. With this method, the azimuth spectrum of multichannel signal can be recovered without aliasing. With the recovered signal, further imaging processing can be utilized to focus the multichannel signal.
