摘　　要：将匀速运动目标成像特性用于干扰的目的,提出了SAR-GMTI高逼真匀速运动假目标调制干扰方法,确定了关键干扰参数,分析了侦察误差对干扰效果的影响,并采用三孔径干涉对消方法研究了其对GMTI的对抗性能。实验分析结果表明文中所提干扰方法可对SAR-GMTI形成高逼真匀速运动假目标的干扰效果,且干扰功率利用率高、对侦察依赖性较低,是一种先进有效的干扰方法。The modulation jamming method for high-vivid false uniformly-moving targets against SAR-GMTI is proposed by using the imaging characteristics of the uniformly-moving target. Key jamming parameters are determined, and the influence of reconnaissance errors on the jamming effects is analyzed. Besides, the countering performance of the proposed jamming method against GMTI is investigated by using the three-aperture interference cancelling technique. The experimental results indicate that the proposed method is effective to produce false uniformly-moving targets, through which certain ground uniformly-moving targets can be protected against SAR-GMTI. At the same time, the new method is efficient and flexible.
