雷达/红外双模导引头抗箔条干扰研究

摘要

Aimed at the problem of missile against chaff-jamming decoy, the models of chaff-jamming decoy and flight movement, state equation of target relative to missile, measure equation of Radar/IR dual -mode seeker are established in Cartesian coordinate by analyzing the chaff jamming principles, and a kind of method against jamming based on Radar/IR dual-mode seeker is presented. Simulations show that the feature of Radar/IR dual-mode seeker using the method is that detection probability is high, the tracking precision is high, and the miss distance is little. The results verify the feasibility of the method.%针对导弹抗箔条干扰弹问题,通过研究分析箔条干扰原理,在直角坐标系下,建立了箔条干扰弹数学模型、载机机动模型、目标相对导弹的状态方程和雷达/红外双模导引头的量测方程,提出了一种基于雷达/红外双模导引头的抗箔条干扰方法.仿真分析表明雷达/红外双模导引头使用该抗干扰方法检测箔条干扰概率高,跟踪精度高,脱靶量小,验证了方法的可行性.
