无源定位中常用的一种方法是测向交叉定位法。二次测向可以定位,而多次测向原则上可以减少定位误差,但是简单地把各对测向交叉定位的结果平均不能获得最佳的效果。本文介绍一种新的定位法,它在多次测向情况下给出限定标准下的最佳结果。对一例测向误差为均方根值5°的测量用二种方法交叉定位,比较结果表明,新方法定位误差均方根值改善了大约一倍。
One of the most commonly used methods for passive location is the cross-location method. The second direction finding can locate, and the multiple direction finding can reduce the positioning error in principle, but simply can not get the best effect on the average of the cross direction finding results. In this paper, we introduce a new localization method that gives the best results under a limited standard under multiple direction finding. The cross-localization of a case with a measurement error of 5 ° rms is cross-referenced by two methods. The comparison results show that the rms error of the new method is approximately doubled.
