MIMO SAR/MTI SYSTEM DESIGN AND SIGNAL ANALYSIS FOR MOVING TARGET INDICTION

摘要：

Multiple-input multiple-output (MIMO) system is one of the major focuses on research activities for mobile communication. Since late 1990s active studies on MIMO radar system have been done as well. Inspired by recent advances in MIMO radar, the MIMO synthetic aperture radar (SAR) concept was advanced. In this paper,the contradiction between azimuth antenna size (or azimuth resolution) and radar detection range in near space high speed platform SAR/MTI system is analyzed. The technique of multiple -input multiple-output,which can be used to resolve the contradiction, is used in SAR imaging mode. Subsequently, a novel space-time equivalent reconstruction method, which can get a high Performance of detection and location in MTI mode, is presented.
