该文根据目标的散射特性，针对不同的雷达参数，提出一种将所需人造地图中各点的位置转换为时域对应点的方法，然后预先存储到DRFM中。当需要干扰时，DRFM中的数据与接收到的雷达信号进行卷积，然后将结果信号重新传输。经过雷达处理后，得到包含真实信息和干扰信息的合成图。最后对仿真结果进行分析表明，如果雷达参数估计准确，人造地图可以起到良好的欺骗干扰效果。如果不是的话，在一定范围内仍然可以起到很好的覆盖干扰效果
Based on the scattering characteristics of targets, aimed at the different radar parameters, in this paper a method is presented to transfer the position of every point in the desired man-made maps into the corresponding point in the time-domain, and then store them into the DRFM in advance. When jamming is needed, the data in DRFM is convoluted with the received radar signals, and then the result signal is retransmitted. After radar processing a composite map including the real and the jamming information is gotten. Finally, analysis of the simulation result shows that if the radar parameters are estimated accurately, a man-made map can have a good deception jamming effect. If not it still can have a good covering jamming effect in a certain area
