Three-aperture INSAR moving targets detecting and imaging

This paper studies the three-aperture interferometric synthetic aperture radar (INSAR) detecting and imaging processing technique of the moving ground targets, which uses three-port clutter suppression interferometry (CSI) processing to cancel ground clutter, to detect the moving ground targets and simultaneously determine their true azimuth location and radial ground speed and to form the focus moving ground targets' images. This paper describes the principle of the three-port clutter suppression interferometry processing, studies the approach to detect the moving ground targets and determine the true azimuth location and radial ground speed and presents a kind of method using INSAR to form the focus moving ground targets' images. Finally, some typical computer simulation results are presented, which illustrate this technique's availability.
