摘要
针对军事运动目标的保护问题,提出了基于欺骗式动目标的SAR干扰方法,该方法根据收到的雷达信号,调制不同的散射强度和位置信息,模拟产生多个虚假的运动目标,避免了静止场景不能干扰动目标成像的缺点。分析了雷达位置确定误差对欺骗式动目标干扰效果的影响,给出了一种干扰机的布阵方法。仿真证明,欺骗式动目标干扰方法可以达到保护运动目标和向被干扰雷达提供虚假信息的目的。
A jamming method for SAR is proposed for the problem of protecting military moving target. This method uses received radar signal, modulates various RCS and position information, produces multi deceptive moving targets. This kind of jamming can protect moving targets, provide deceptive information to the jammed SAR, avoid the shortcoming of unable to protect moving target of stable scene. This paper discusses the configuration of jammers and the effects of the estimation error of radar＇ s position, and lastly gives the simulation result, which testifies the effectiveness of this jamming method.
