摘　　要：机载单站无源定位技术正成为当前精确定位技术的研究热点,基于方位角变化率,建立了空间定位模型,针对目标机动,噪声统计特性不确定等实战环境,引入鲁棒控制理论中的H∞滤波,提出了一种新的定位跟踪算法,仿真结果表明,该方法增强了定位系统的鲁棒性,具有较好的定位性能。Passive location of a single aieborne pbserver is becoming the hot topic today in accurate positioning. The aieborne passive location model is built based on azimuth angle changing rate. Considering the combat environment of target maneuver and uncertain noisy satisical feature, H∞filter in robust control theory is introducted. A new algorithm in locating and tracking is proposed. The simulation results show that the rebustnessof locating system is enhanced and the locaing property is imoroved.
