声纳无源工作时可以通过测量时差进行定位。本文对平面三声纳基阵无源时差定位系统的定位过程中可能出现的模糊现象进行了探讨，找出了模糊分布与布站以及观测噪
声方差大小之间的规律，得出了模糊分布与布站之间的关系，并提供了一些解决方法。
关键词：声纳，时差定位，模糊，布站
Abstract: If a sonar operates passively, it can obtain the location of object by measuring the
TDOA. The problems of possible ambiguity in 3-Station TDOA Location systems are discussed. We find out the relation between ambiguity and the placement of stations, and the laws of the placement of ambiguity and the placement of stations、the intention of measuring noice. Further more , We present several solutions.
Key words: Sonar, TDOA location, ambiguity, the placement of stations
