| 摘 要： | 声呐无源工作时可以通过测量时差进行定位．对平面3声呐基阵无源时差定位系统的定位过程中可能出现的无解现象进行了探讨，找出了无解分布与布站以及观测噪声方差大小之间的规律，并在各种布站及噪声条件下，对布站与无解分布的关系进行了仿真，直观反映了不同布站形式对时差定位的影响．针对不可避免的定位无解情况，提供了具体的无解问题的解决方法，并根据无解分布规律，提出了最优布站的3个原则．

| Abstract: | If sonar is operated passively, it can obtain the location of object by measuring the TDOA, possible problems of Non-solution in 3-Station TDOA Location system are discussed. The relationship between Non-solution and the placement of stations, the placement of stations and measuring noise are found out. The effect between the lion-solution and the placement of stations is simulated under different placement of stations and measuring noise. Furthermore, several methods are presented to solve the problems. Finally three optimal distribution principles for target location are given. |
