Novel method for ground clutter cancellation of low speed targets based on space-time adaptive processing

A new clutter model for multichannel SAR based on the analysis of features of space-time adaptive processing and SAR imaging is given. Based on this model, a new clutter cancellation algorithm suitable for multichannel SAR is proposed. A processing scheme for moving target imaging is also given. It is shown in simulation that the new method can effectively reduce the power of mainbeam ground clutter for low speed target imaging.
