A Spaceborne Multi-channel SAR Imaging Algorithm for Moving Targets

Spaceborne multi-channel SAR is an effective means to achieve high-resolution and wide-swath imaging. Due to the signal undersampling, the unambiguous spectrum reconstruction should be conducted firstly. However, the channel imbalance will cause the failure of reconstruction. For moving targets, the motion will result in inter-channel phase error. Different motion speeds correspond to different ph...
