在建立电磁脉冲弹和相控阵雷达天线阵面弹目关系数学模型的基础上，对电磁脉冲弹使用过程中涉及到的天线阵面覆盖率等问题进行了研究，分析了弹道偏差等因素对天线阵面毁伤区域的影响，并进行了仿真计算。仿真结果分析表明，弹头引爆高度、落点精度等弹道参数对毁伤覆盖区域均会产生影响。为实现对目标的最佳毁伤效果，应综合考虑弹头引爆高度、弹道倾角、滚转角等参数精度，以及目标处功率密度等要求。

Based on the simulation model of the space location relationship between electromagnetic pulse (EMP) bomb and phased-array radar antenna, the coverage ratio of the antenna and other parameters were discussed. The influence of trajectory deviation on the coverage area of the antenna was analyzed, and simulation was also carried out. The simulation results show that some relevant parameters including initiating height and fall point accuracy can influence the coverage area to the phased-array radar antenna. In order to reach the best damage to the target, the accuracy of initiating height, trajectory tilt angle, roll angle and other parameters, and the power density of the target should be considered synthetically.
