Abstract

Abstract:

A study has been made of detecting the ground slow moving target with the dual-satellite mode. Utilizing the method of SAR-GMTI we adopt dual satellites to realize the detection of very slow ground targets, but the problem of blind speed arises. We design the satellites to work at several different operating-frequencies, thus overcoming the problem of blind speed. Meantime the targets can be orientated easily. Analyse or simulations of this method under different conditions are also made.

Key words: dual-satellite, SAR, GMTI, blind speed, target orientation
