多角度合成孔径雷达成像技术研究进展

摘要

Multi-angle synthetic aperture radar imaging detection technology may effectively solve out the problems existing in traditional single-angle synthetic aperture radar imaging like target shad-ing and layover distortion.In three respects like multi-angle synthetic aperture radar imaging theory, imaging algorithm and current technical applications,the paper introduces current domestic and inter-national development of multi-angle synthetic aperture radar imaging technology,concludes and ana-lyzes key technologies like target scattering property modeling,observation angle step optimization, transmitting waveform design and imaging algorithm for multi-angle synthetic aperture radar and looks into the trend of imaging processing and practical applications.%多角度合成孔径雷达成像探测技术，可有效解决传统单角度合成孔径雷达成像中存在的目标遮挡和叠掩问题。从多角度合成孔径雷达成像理论、成像算法和技术应用现状3个方面，详细介绍了多角度合成孔径雷达成像技术的国内外发展现状，总结分析了多角度合成孔径雷达成像目标散射特性建模、观测角度间距优化、发射波形设计、成像算法等关键技术，最后展望了其在成像处理和实际应用两方面的发展趋势。
