In the technique of ground moving target indication using SAR (SAR-GMTI), the image resolution has great impact on the target detection performance. A SAR image resolution selection scheme is proposed in this paper. Performance of target detection at different image resolutions is analyzed in view of the detection probability. Based on the analysis and taking a target with classical RCS as an example, optimal SAR resolution for different target size is given. Simulation results indicate that the scheme can be widely used in engineering practice.
