基于DRFM的高分辨雷达扩展目标回波仿真技术

介绍了一种基于DRFM的高分辨雷达扩展目标回波信号仿真方法,该方法将舰船等复杂目标视为扩展目标,其雷达回波信号可以看作扩展目标各散射中心产生的回波信号的叠加。应用该技术产生的模拟目标回波信号和假目标干扰信号,由于携带雷达发射信号和照射目标特征信息,能顺利进入末制导雷达接收机,仿真效果优于一般常规仿真技术。

Extended Target Echo Simulation of High-Resolution Radar Based on DRFM

In this paper, article proposed a simulation method of high-resolution radar extended target echo signal simula? tion was proposed based on DRFM. If ships and warships were regarded as extended targets, the radar echo signal would be the superposition of each scattered center echo signal. Analog target echo signal and false target jamming signal generat? ed by this method carried the radar emission signal and irradiation target characteristic information effectively, and could pass the threshold voltage of terminal guidance radar. Therefore the method was better than general conventional simula? tion techniques.
