Abstract
The multichannel ground moving target indication system based on the synthetic aperture radar ( SAR-GMTI) can obtain high resolution SAR images of stationary scene and detect slowly moving targets in the region with strong clutter interference simultaneously,therefore it plays an important role in military and civil applications. Firstly,with regard to multichannel SAR-GMTI,this paper gives a brief introduction to the basic conception,and comparisons between airborne and spaceborne systems,simultaneous processing of SAR imaging with GMTI and time-sharing processing. Afterwards, it systematically presents the ad-vances abroad and domestic. Then two directions are analyzed emphatically which are distributed space borne SAR-GMTI and the SAR-GMTI system based on multiple-input multiple-output( MIMO) . Finally, the research emphasis of SAR-GMTI system is discussed,along with its promising prospect.关键词
