Abstract: 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.. -
