无源测向定位的地球椭球面算法

Earth Ellipsoid Algorithm for Passive Bearing-only Location

文章介绍一种不需要解方程组,考虑地球椭球的无源测向定位算法,给出了计算过程和支持软件代码实现的详细描述,并做了算法验证,利用试验测量数据得到了定位结果,与试验设备的定位结果做了比较,同一测量时刻同样的测量数据,本文的定位误差明显小于试验设备的定位误差。

This paper introduces a passive bearing-only location algorithm considering earth ellipsoid without solving equations, presents the counting process and realization of software code and the verification of algorithm is made. The tests were carried out on measuring data and the location result is gained. A comparison of location result of the equipment with the gained location result is made under conditions of same time and measured data, and the location error in this paper is more significant than the test equipments.
