| 摘 要： | 极化SAR已成为SAR技术的研究热点,本文针对极化SAR中有源干扰(包括有源压制干扰和有源欺骗干扰)的抑制问题进行了研究.通过分析多通道极化SAR(M-PolSAR)系统中的信号模型及干扰模型,提出了一种结合极化与多通道技术的有源干扰抑制方法.通过快时间域的STAP技术和慢时间多普勒域对消,对包括压制和欺骗的有源干扰进行有效的抑制,给出了抗有源干扰的PolSAR成像的工程实现流程.仿真实验验证了该方法的有效性.

| Abstract: | Polarimetric SAR now is a hot spot in SAR research.This paper mainly deals with the active jamming(induding both blanket jamming and deceptive jamming) suppression in polarimetric SAR.On the basis of the analysis of signal and jamming models in the multichannel polarimetric SAR(M-PolSAR system),a novel method for active jamming suppressing is proposed by combining the polarimetric technique with multichannel technique.By operation of the fast-time STAP and cancellation in Doppler domain,the active jamming h... |
