| 摘 要： | 针对多基站雷达系统在实际工程中由于地形因素或任务条件影响而无法进行规则布站的问题,文中对各种非规则布站条件下的系统定位精度进行理论仿真分析。文中分别从布站的基线长度、基线间夹角和基站间高度差3个方面研究非规则布站对系统定位精度变化的影响,发现在各种条件的非规则布站方式下,系统在不同定位区域的定位精度分布规律。该结果可为实际工程中多基站雷达的站址选择提供理论依据。

| Abstract: | In view of the problem that multi-base station radar system can not be regularly deployed due to the influence of topographic factors or mission conditions in practical engineering, the system positioning accuracy under various irregular station distribution conditions is analyzed by theoretical simulation in the current study. The influence of irregular station distribution on the system positioning accuracy is investigated from three aspects including the baseline length, the angle between baselines and the height difference between base stations. The location accuracy distribution law of the system in different locating areas under various conditions of irregular station distribution is obtained, which provides a theoretical basis for site selection of multi-base station radar in practical engineering. |
