四站时差定位测高精度的仿真研究

Simulation of Hypsometry Accuracy Using 4-station TDOA

无源雷达的测高精度是困扰其从两坐标雷达发展为三坐标雷达的关键问题.基于时差定位测高精度原理,考虑各种因素对测高精度的影响,并通过计算机仿真,对倒三角形布站进行了分析,提出了最佳的布站方案.

Based on the TDOA, the hypsometry models of 3-D emitter using 4-station TDOA and hypsometry error models were discussed, and the curves and their simulation results were given. Finally an optimal distribution scheme for 3-D target location was given.
