Novel Method For Ground Clutter Cancellation Of Low Speed Targets Based On Space-Time Adaptive Processing

A now clutter model for multi-channel SAR based on analysis of the features of space-time adaptive processing and SAR imaging is given, On the foundation of this model, a new clutter cancellation algorithm suitable for multi-channel 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 main beam ground clutter for low speed targets imaging.
