相比静爆测试，战斗部动爆测试能够为**系统评估提供更为准确的数据。在进行动爆测试时，波束宽度的选择将会直接影响测试时间点的选择。通过对战斗部动爆破片运动的分析、建模与仿真，分析了动爆破片的飞散和运动情况。同时，针对利用雷达进行动爆测试的技术手段，分析了雷达波束内的动爆破片数量、速度、距离分布等特性，并重点针对雷达波束宽度对战斗部动爆破片雷达特性的影响进行了分析。分析结果能为动爆测试技术的发展提供进一步的理论依据。

Dynamic tests to warhead can provide more exact data for weapon system evaluation than static tests.The choice of beam-width in the test has direct effect on the choice of test point.Based on analysis, modeling, and simulation to movement of warhead dynamic fragments, the dispersion of the fragments was studied.Meanwhile, by using radar in the warhead dynamic test, the characteristics of the fragments, such as quantity, velocity and distance distribution in radar beam-width, were analyzed, with focus on the influence of radar beam-width to radar characteristics of warhead fragments.The result is helpful for the development of warhead tests.
