主要探讨了有源干扰星载SAR的技术措施———有源压制干扰和有源欺骗干扰。有源压制干扰主要包括阻塞干扰、瞄准式干扰和随机脉冲干扰;有源欺骗干扰主要包括转发式干扰、应答式干扰和散射波干扰。定性分析了各种干扰对SAR图像影响效果并对有源干扰所需干扰功率进行了定量计算。

This paper discusses the technology about active jamming space-borne synthetic aperture radar(SAR),including noise jamming and deception jamming.Noise jamming includes blocking,aiming and random pulse jamming,and deception jamming includes transmitting,responding and scattering jamming.At the same time,this paper qualitatively analyses various jamming effect on SAR image.At last,this paper computes the active jamming power needed.
