N2 - Ground clutter is the main interference in the ground moving target detection and imaging. In the three-channel SAR-GMTI system, echo signals from each channel are compensated, and then canceled between two channels to suppress clutter. But it is difficult to achieve the good effect of clutter suppression for the spaceborne system because of the earth rotation. The detailed reason is analyzed from two aspects, i.e., the three-channel signal processing algorithm and the space-time adaptive processing (STAP) theory. In order to suppress clutter greatly, a new technique is presented in this paper to perform yaw and pitch steering. This technique is compared with the attitude steering technique currently applied and gets a better result This paper also analyzes the performance of the spaceborne three-channel SAR-GMTI system, including the minimum detectable radial velocity and the velocity estimation error.
