%X Multi-channel SAR system can avoid the minimum antenna area constraint, thus achieving wide swath and high resolution SAR image. There are more deleterious factors in multi-channel SAR system compared with single-channel SAR system, which may degrade the quality of SAR image greatly. In this paper, all the deleterious factors in the system are analyzed and classified according to their impact on the SAR imaging processing, and approaches of array error estimation and its compensation are presented, respectively. The validity of the proposed method is verified by experimental results of measured Tri-channel SAR data.
