一种提高车载机动雷达对抗ARM生存概率的方法

A method of enhancing survival probability of vehicular mobile radars against ARM

为提高车载雷达机动作战时的生存能力,研究了车载机动雷达采取间歇辐射工作方式降低反辐射导弹(ARM)命中精度的问题。首先对雷达间歇辐射对抗ARM机理进行分析,推导建立机动雷达在不采取和采取机动间歇辐射战术时ARM攻击雷达的命中误差模型。通过仿真分析,结果表明车载机动雷达机动作战时选取恰当的关开机时间比可以极大降低ARM的命中精度,提高车载机动雷达对抗ARM的生存概率。

The problem that the working mode of intermittent radiation is adopted to reduce the hit accuracy of the anti-radiation missile （ARM） for the vehicular mobile radar is studied to improve the radar＇s survivability on the battlefield. The theory of radar intermittent radiation against the ARM is analyzed, and two hit error models are derived when the ARM attacks the vehicular mobile radar with or without intermittent radiation. The simulation results indicate that the hit accuracy can be greatly reduced by selecting proper off/on time ratio, which enhances the survival probability of the vehicular mobile radar.
