从InSAR,SAR-GMTI和双/多通道对消技术3个方面介绍了多通道SAR的发展历程,总结了其抗干扰技术的研究进展,并着重总结分析了多通道SAR干扰技术的发展现状。抗干扰方面,主要从天线及体制、信号波形两个角度进行了归纳,并分析了双/多通道干扰对消技术的特点。干扰方面,分析了多通道SAR干扰技术的发展趋势,重点探讨了复杂调制、相干性、多站分布式干扰和针对多通道SAR抗干扰技术等问题。

The historical development of multi-channel Synthetic Aperture Radar (SAR) system is presented from three aspects of InSAR,SAR-GMTI and dual-/multi-channel cancellation technique,and theresearch progress of Electronic Counter-Countermeasure (ECCM) is summarized with focus on the status quo of multi-channel SAR ECM technique.With regard to multi-channel SAR ECCM,an introduction is made from two aspects: antenna/structure and signal waveform,and the characteristics of dual-/multi-channel cancellation technique are analyzed.As to multi-channel SAR ECM,the prospect of ECM is analyzed emphatically,and emphases are laid on the complexity of modulation,the coherency of interference,the multi-station distributed countermeasure and the multi-channel SAR ECCM.
