基于方位角变化率的快速高精度无源定位方法

Passive Location Method with High Precision and Fast Convergence Based on Changing Rate of the Angle of Arrival

在分析现有单站无源定位方法优缺点的基础上,根据运动平台对固定目标无源定位技术的特点,提出了一种通过方位角变化率信息对观测站与目标间距离进行解算的快速高精度无源定位方法。并通过仿真,验证了该方法是一种高精度、快速的定位方法,具有较强的通用性。其主要应用于机载无源探测设备对地面固定雷达站或其他辐射源定位,从而为引导导弹对其攻击提供必要的数据。

On the basis of analyzing the advantages and disadvantages of present passive location methods of single station and according to the technology characteristics used for mobile platform to locate the fixed targets passively, a passive location method with high precision and quickness is put forward via resolving changing rate of the angle of arrival between observation station and the target. Simulation verifies the higher precision and better versatility of this method. It is mainly used for airborne passive detection equipment to locate fixed radar station or other radiation source on the ground to provide necessary data for missile attack.
