| 摘 要： | 讨论了由两天线SAR的干涉图像对地面动目标进行检测的原理，根据线性调频信号的时频强耦合性及目标回波的特点，在接收到的雷达发射信号上进行距离和方位向移频处理，继而转发。经仿真分析，在干扰能量较大的情况下，在假目标基础上进行的移频干扰可以产生假的动目标，进行欺骗干扰。在雷达发射信号上进行随机时延、频移及相移可使得真实动目标丢失或者检测出现错误，产生遮盖性干扰。

| Abstract: | The principle of moving targets detection using the dual-channel images is discussed.The relationship between frequency and time is analyzed.Then the two-dimension shift-frequency jamming is added to change transmitting signals' frequency and phase and retransmitted.By the simulation,at a high noise-signal rate it produces deception jamming by shifting frequency and phase of false targets.If adding random time-delay,frequency and phase-increase to radar transmitting signal,some real targets is lost and some... |
