摘要
无源定位雷达系统本身不辐射电磁信号,因此能够有效地保护己方的安全。双站交叉定位技术是一种准实时的无源定位技术,在军事领域应用非常广泛。首先研究了双站交叉定位的定位原理,分析了在雷达测角精度、基线测量精度一定的情况下定位误差与雷达布站的关系。给出了定位误差与雷达布站的数学模型,对不同条件下的定位误差进行了仿真,在分析仿真结果的基础上,得到了定位误差与雷达布站的基本规律,为雷达布站问题提供了理论参考,具有一定的工程应用价值。
Passive radar doesn＇t radiate any electromagnetic energy, which can safe itself efficiently. Double station cross location belonging to passive location technology has been widely used in military region. The article examines the theory of double station cross location. And then the relations between location error and radar configuration is studied when the radar angle and base line precision are given. The maths model of location error and radar configuration is proposed. The simulation results present the principle of location error and radar configuration. It is valuable to analyze the radar configuration in theory and application.
