摘要
针对载机雷达被干扰或无源探测系统定位精度有限条件下空空导弹无法正常发射和制导攻击辐射源目标的问题,提出了一种战斗机机载无源雷达与机载远程反辐射导弹组网协同测时差定位策略。建立了机弹协同测时差无源定位算法及精度分析模型,对单纯采用时差定位误差较大的情况,引入了修正增益卡尔曼滤波算法提高系统预测精度。经过仿真验证,引入滤波器后系统的定位精度有了很大提高,可以对预警飞机等高价值电磁辐射目标远距离精确定位,为对辐射源进行打击和干扰提供了重要信息保障。
Aimed at the problem incapability carrier aircraft＇ s radar is jammed, or the airborne pas of guiding the launch of airtoair missiles when the sive detection system＇ s positioning accuracy is relatively low,a strategy of time difference of arrival （TDOA） passive location using a network of fighter＇ s airborne passive radar and airborne long-range anti-radiation missile is proposed. The models of TDOA passive location by aircraft-missile cooperation and accuracy analysis are established. Aimed at the prob- lem of larger error using single time difference location, a modified gain extended Kahnan fiher （MGEKF） is introduced to improve the system＇s forecasting accuracy. Simulation results show that the system ＇ s location accuracy is improved greatly by introducing the filter, which can he used to locate high altitude Early Warning Airplane targets precisely at long range, and provide important information support for attacking and jamming of radiation sources.
