摘　　要：双基地与单基地声纳相比,具有较好的反电子对抗的能力。但是在某些区域(如基线区、发射和接收站的侧边区),其定位性能较差。为了改善这些区域的定位性能,最有效的办法就是增加发射和接收站的数量,形成多基地声纳系统。而对于多基地声纳系统而言,不同的站址布局,算法的定位精度也不会相同。给出了多(四)基地声纳系统定位布站的几何分类,通过多基地TOL算法仿真分析了各种布站的定位精度,得到了多基地定位布站方案,方案可得到比较理想的定位精度,工程易实现,具有较强的应用价值。Compared with the monostatic sonar, bistatic sonar has preferable ability in anti -electron confront. But in some districts （ such as baseline districts, side districts of emitting stations and receiving stations）, its localized accuracy is bad. For improving the accuracy of localization of these districts, the most effective method is to increase the amount of emitting stations and receiving stations. Then the muhistatic sonar system is formed. Multistatic （4 -station） sonar disposition＇s geometric figure classification of position location using muhistatic TOL algorithm is provided. By the simulation analysis of localized accuracy for muhistatic sonar system, a 4 - station disposition scheme is obtained, in which the perfect localized accuracy is got. The proposed disposition scheme is available for real application.
