摘　　要：机载投放的箔条云是空空导弹无线电引信常见干扰,为了分析无线电引信遇见箔条云的可能性,提出一种无线电引信箔条干扰风险分析方法。根据目标的飞行轨迹和比例导引法计算出末制导段的导弹飞行轨迹,利用适用于箔条高速运动的箔条云整体运动模型模拟引信工作时间段内目标投放的箔条云,并根据箔条是否落入引信探测波束范围内判断引信是否遇见箔条云。仿真结果表明当导弹尾后攻击目标时,该方法可分析无线电引信遇见的箔条数目密度,为设计无线电引信抗箔条干扰算法的启动条件提供依据。Airborne chaff cloud is often used to jam the air-to-air missile radio fuze. In order to analyze the encounter possibility of radio fuze and chaff cloud,a chaff jamming risk analysis method of radio fuze is proposed. The missile flight path in terminal guidance section is computed according to the target flight path and proportional navigation method,several chaff clouds launched by the target during the radio fuze working time are simulated by the holistic kinetic model of chaff cloud suited for high speed,and then the judging whether the radio fuze encountered chaff cloud is done in accordance with whether the chaff is in the range of the radio fuze detection beam. The simulation result shows that the method can analyze the encountered chaff number density of the radio fuze when the missile attacks the target in the stern chase state,and provide basis for the design of the radio fuze anti chaff jamming algorithm＇s starting conditions.
