摘　　要：全球卫星导航反射信号(GNSS-R)移动目标探测技术是一种针对目标区域进行遥感探测的新型探测手段.从技术机理上,GNSS-R移动目标探测技术为无源双基地雷达,具有与有源雷达截然不同的信号传播模型.通过分析GNSS信号传播的几何构型,对监测区域特征进行分析,判断探测区域是否出现移动目标.经过实验验证,当移动物体经过监测区域,系统能够准确地探测到移动目标并计算出目标高度及位置信息.The mobile target detection technology based on GNSS-R is a new remote sensing detection method that uses the reflection signal of global satellite navigation signals to remotely detect the target area.From technical perspective,the GNSS-R mobile target detection technology is a passive bistatic radar.By analyzing the geometric configuration of GNSS signal propagation,the characteristics of the monitoring areal feature are analyzed to determine whether there is a moving target in the detection area.after experimental verification proveds that,when a moving object passes through the monitoring area,the system can accurately detect the moving target and calculate the target height and position information..
