摘　　要：现有的末制导雷达电子干扰仿真评估试验对弹道解算模型进行了较大简化,普遍采用质点模型,使得仿真结果严重失真。讨论了六自由度闭环弹道仿真中的脉冲多普勒雷达导引头(PDRS)相干视频仿真,并针对典型的速度波门拖引干扰场景进行了仿真试验。结果表明速度波门拖引干扰对角度跟踪回路无直接影响,仅影响了角速度估计的收敛性,导致制导精度并无太大变化。该结论和暗室测量结果相吻合,表明PDRS相干视频模型用于6自由度闭环弹道仿真非常准确,为战术巡航导弹的参数设计和性能评估提供了一个有效和实际的解决方案。According to existed experimental evaluation of radar electronic jamming simulation for terminal guidance, the ballistic calculation model was simplified relatively. Particle model was usually adopted which made simulation results have serious distortion. The pulse Doppler radar seeker was discussed in six degree of freedom trajectory simulation of the closed loop(PDRS) for coherent video simulation, and simulation results show that the VGPO has no direct effect on the angle tracking loop, just through guidance filter affects the convergence angle velocity estimation, which leads to little change of guidance precision. The conclusion and anechoic chamber measurements results show that the PDRS of coherent video model for 6 degree of freedom closed-loop trajectory simulation is accurate, which provides an effective and practical solutions for parameters designing and performance evaluation of tactical cruise missile.
