摘　　要：三通道SAR-GMTI检测运动目标的效果及运动目标的定位受到众多误差因素的影响。本文在定义通道隔离度理论模型的基础上,结合三通道SAR-GMTI的基本原理对三通道SAR-GMTI受通道隔离度的影响进行了理论分析,并通过仿真给出了对运动目标检测以及运动目标定位的误差曲线。Detecting performance and locating accuracy of three-channel SAR-GMTI against moving targets are affected by many error factors. On the basis of theory model of channel isolation, impact of channel isolation on SAR-GMTI is analyzed theoretically based on basic principle of three-channel SAR-GMTI; and detecting result and locating error curve against moving targets obtained in simulation is given.
