为了评估电子干扰条件下防空导弹的射击效能,建立基于防空导弹空间杀伤区射击次数计算模型,根据功率压制准则计算防空雷达受到远距离支援干扰时对目标的探测距离。对防空导弹雷达受到干扰时的射击次数进行仿真计算,得到不同高度和不同航路捷径下防空导弹对目标的射击次数和杀伤概率,为电子干扰条件下防空导弹的射击效能评估提供可行的方法。仿真结果表明,远距离支援干扰大幅度降低防空导弹的射击效能。

In order to assess the firing effectiveness of anti-aircraft missile under the electronic interference conditions, the paper established calculation model of firing time based on the space kill zone of anti-aircraft missile, the detection distance of air defense radar under long range support interference, and the firing time were also calculated when the air defense missile radar was disturbed the firing frequency and killing probability of anti-aircraft at different altitudes and different route shortcuts were obtained. It provides a feasible method for evaluating the firing efficiency for anti-aircraft missile under the condition of electronic interference. The simulation results show that long range support interference greatly reduces the firing efficiency of anti-aircraft missiles.
