| 摘 要： | 针对伪码调相脉冲多普勒引信目标模拟器的视频回波信号进行建模与仿真.分别对目标回波进行了建模,将目标用若干个等效散射点表示,考虑了各散射单元的相干作用,对遮挡进行了近似处理;对天线照射区域内的杂波进行了分割,采用近似目标回波的处理方法对杂波进行了建模,并将该方法应用到引信目标模拟器中.仿真结果证明了目标和杂波建模的正确性和可靠性.

| Abstract: | Echo modeling and simulation in a PD fuze target simulator for phase modulation by pseudo random coding are studied.A model of fuze target is built up with equivalent scattering point.Interaction between scattering points is discussed and shadowing is treated with approximation.The cluttering area wherein the fuze antenna illuminates is distributed into small clutter cells and the clutter modeling is built up as the method of fuze target echo modeling.Validity of the model of fuze target and clutter were proved by simulation results. |

| Keywords: | pulse Doppler fuze target model clutter model modeling and simulating |
