摘　　要：基于亮点法建立了目标位于雷达近场时的系统模型。讨论了目标回波信号的幅度、相位和时延的计算方法。利用时域有限差分法,建立引信雷达天线产生的近场特性数据库。将板级电路仿真和天线近场计算结合起来,建立引信系统仿真器。通过这个仿真器可以更加精确可靠地对引信系统进行仿真。最后时域仿真结果证明这种仿真器可以有效地应用到武器系统的模拟仿真中。Based on the highlight method,this paper builds up the model of the radar target especially the near field.The method of computing the target echo signal amplitude,time delay and Doppler shift is discussed.The database of the properties of near field,which is generated by the fuse antenna,is made using FDTD method..Combining simulation of board-lever circuit with computing of near field,the simulator was made for fuse system.And by means of this simulator the imitative analysis and calculation on fuse system can be more reliable and accurate.In the end the result of time-domain simulation demonstrate that the simulator can be effectively applied in the synthetic test system to the fuse of the weapon system.
