Abstract :
Jamming and clutter must be effectively suppressed for moving target detection. A method of detecting slow-moving ground targets based on three-aperture synthetic aperture radar (SAR) in the presence of blanketing jamming is presented. It uses two-aperture cancellation method to suppress SAR jamming to target then to detect the moving ground targets. Firstly, spatial geometry model and echo signal model of three-antenna SAR were built, then an algorithm of SAR moving target detection based on clutter suppression interferometer (CSI) was derived, and the realization steps were presented. Finally, computer simulation results validate its effectiveness.
