摘要
在分析现有单站无源定位方法优缺点的基础上,针对运动平台对固定目标进行无源定位要求快速性这一特点,提出了一种通过目标角度和角度变化率信息对观测站与目标间的距离进行解算的快速定位方法,依照定位误差的几何分布(GDOP)对该方法进行了单次和多次定位精度的仿真,验证了该方法是一种高精度的、快速的定位方法.
Based on the analysis of advantages and disadvantages of present single station passive location methods, and contrapossing the characteristics of fast locating immobile targets with mobile platforms,a fast passive location method has been put forward in this paper via resolving the relations of angle and its changing rate between observation station and the target. According to the GDOP （Geometric Dilution of Precision） of location error,the simulation of location precision with single or multiple times validates its high precision and quickness.
