摘　　要：基于动目标分辨力外场试验设计需求,研究了单通道SAR/GMTI雷达动目标分辨力。首先给出了单通道SAR/GMTI系统动目标检测条件。其次基于动目标距离分辨力、方位分辨力及联合分辨外场试验条件,给出了SAR雷达回波多普勒数学表达式和动目标分辨力表达式。最后进行了单通道SAR/GMTI动目标分辨力数字视频仿真,证明了分辨力理论分析的正确性。Based on the experimental design demand of moving target resolution in external field, the moving-target resolution of single channel synthetic aperture radar ground moving target indication（ SAR/ GMTI） radar is studied. Firstly, the detection condition of single-channel SAR/GMTI radar system is presented. Secondly, based on the external field experimental condition of range resolution, bearing reso- lution and joint resolution of moving target, the echo Doppler mathematical expression and the moving tar- get resolution expression of SAR radar system is offered. Finally, the numerical video simulation of mov- ing target resolution of single channel SAR/GMTI radar is proposed, which verifies the validity of this the- ory analysis.
