N2 - Attitude jitter will cause zygomorphous paired-echoes after azimuth focusing for traditional spaceborne SAR system. However, for multi-channel spaceborne SAR system, attitude jitter of one sub-antenna will not only cause the paired-echoes but also affect other sub-antennas. This paper first built the model of antenna jitter for multi-channel SAR system. As a next step, the amplitude and position of paired-echoes secondary derivative paired-echoes were illuminated by mathematic derivation. Moreover, the effects of satellite attitude jitter on multi-channel SAR image qualities were analyzed as well. Finally, the simulation results justified the validity of theoretical analysis results.
