| 摘 要： | 为了得到无源雷达菱形布站的最佳布站方案,分析了时差定位算法的基本原理,推导了定位精度的数学模型,考虑了影响定位精度的各种因素。通过计算机仿真实验对比了在不同主站位置、不同站间距离以及不同主站高度的情况下菱形布站的GDOP(geometric d ilution of precision)等值线分布,最终得出了定位精度与布站之间的联系,为无源雷达最优菱形布站提供了理论依据。

| Abstract: | To get the optimized deployment for rhombus model of passive radar,the time difference of arrival(TDOA) algorithm is analyzed;orientation precision model is deduced;factors of affecting orientation precision are investigated.Given different locations of main station,different distances between stations and different altitudes of main station,GDOP isoline distribution are compared with simulation experiment.Finally,the relationship between orientation precision and deployment is gained,which provides a theor... |
