| 摘 要： | 在推导五站时差无源定位和定位精度的基础上,重点分析了正方形、Y形、T形、五边形等典型五站布站的定位精度;分析了布站基线长度、布站高度等因素对定位精度的影响;分析了空间机载无源侦察系统的四种不同布站方式的定位精度.仿真结果表明,五站时差无源定位精度与布站方式密切相关,工程应用应根据不同需求选择适合的方案.

| Abstract: | Passive location using TDOA（ time difference of arrival）and its location precision are deduced, and GDOP（ geometrical dilution of precision）of representative 5-stations of square, Y, T, 5sides are ana- lyzed. Then the relationship between length of based line, height of stations and GDOP are discussed. GDOP of passive location of 5-stations based on TDOA is connected closely with location style by simulation result, engineering application should choose adaptive case according to different requirement. |
