双基地声纳探测范围分析

双基地声纳在一定程度上综合了单基地主动和被动声纳的优点，具有扩大探测范围的优势，但并不能够在全方位上都获得探测距离优势，在某些方位上甚至不如等效单基地声纳。在双基地声纳系统中，根据能量关系推导出双基地声纳系统最大可探测范围的数学模型，并进一步定量分析了基线长度、等效半径与探测范围和各个方位上的探测距离的关系，提出了优势区域、优势角的概念。在此基础上，给出了不同情况下双基地声纳的几种优化使用配置方案。

An Analysis on the Detectable Region for Bistatic Sonars

Bistatic sonar, which inherits the merits of active and passive monostatic sonars to some ex?tent, has the advantage of extending detectable area. But it can’t obtain the desirable detectable area at all angles, and the detectable area may be inferior to what the equivalent monostatic sonar has at some angle. Based on the energy relationship, the model of detectable region for the bistatic sonar was established, and the relation between the detectable range and the azimuth angle at different baseline length, equivalent raidius and detectaole area was analyzed. Ihe notion of advantage region and advan?tage angle was put out. The optimal configuration of bistatic sonar were put forward under some cir?cumstances .
