| 摘 要： | 本文给出了一种三维被动定位方法。该方法利用三元水平阵和二元垂直阵实现对目标的三维定位。由三元水平阵首先求得目标斜距和目标方位,在此基础上利用垂直阵估计目标深度坐标,最后综合已有测量结果来求解目标水平坐标。本文还通过仿真分析了该方法的定位性能。

| Abstract: | A method to 3-D passive localization is presented.Localization of the target is realized using 3-element horizontal array and 2-element vertical array.Firstly,we estimate the slanting distance and the azimuth of the target by the horizontal array,from which quantities we can get the depth of the target by the vertical array.Lastly,we solve for the horizontal coordinate on synthesizing the existing results.The simulation results analyse the localization performance of the method. |
