车载式机动雷达间歇关机对反辐射导弹命中精度的影响

摘要

In order to improve the survivability of the radar w hen it is in mobile campaign ,this paper studies the influence of intermittent shutdow n of vehicular mobile radar on hit probability of anti-radiation missile (ARM ) attack .According to the main error sources that influence the hit accuracy of ARM ,the math simulation model of hit error of ARM attack radar whether the vehicular mobile radar adopts intermittent shutdow n tactics or not ,the simulation result show s the influences of ra-tio of radar running time to shutdown time ,running time and ARM parameters on hit probability of ARM ,and indicates that hit accuracy can be reduced greatly by adopting proper ratio of radar run-ning time to shutdow n time through the analysis ,w hich is helpful to enhance the survival probabili-ty of vehicular mobile radar .%为提高雷达机动作战时的生存能力，研究了车载式机动雷达采取间歇关机战术时对反辐射导弹攻击命中概率的影响。根据影响反辐射导弹命中精度的主要误差源，建立了车载式机动雷达在不采取和采取间歇关机战术时反辐射导弹对雷达命中误差的数学仿真模型，仿真结果反映了车载式机动雷达关开机时间比、开机时间值以及反辐射导弹自身参数对反辐射导弹命中概率的影响，并通过分析表明车载式雷达机动作战时选取恰当的关开机时间比值可以极大地降低反辐射导弹的命中精度，提高雷达的生存概率。
