InISAR imaging systems generally employ a multi-antenna pair model with orthogonal properties. In practical applications, there may be amplitude and phase errors in different antenna receiving channels, and the obtained ISAR target echo signal also has errors. Although several algorithms have been proposed, these algorithms can only work with no amplitude and phase error. This paper proposed an algorithm to achieve three-dimensional ISAR imaging based on the channels with amplitude and phase errors. The simulation results show that the proposed algorithm has good performance.
