舰机双基地协同主动声探测范围分析

Cooperative Active Acoustic Detection Range Analysis of Ship and Aircraft Bases

针对双基地声呐有效作用区域分析过程中模型较为简单的问题,提出了在目标强度不均匀情况下双基地覆盖面积的计算方法,得出了盲区和双基地最优配置的结论。仿真计算发现,双基地覆盖面积随潜艇航向的改变呈蝶形变化,并且双基地在工作时只有在特定区域内才会比单个等效合置基地有优势,通常称该区域为优势区域,通过仿真计算得出优势区域内存在盲区的基线距离。潜艇被发现后,通常在一定的概略角内进行逃逸,通过仿真计算,发现双基地具有距离优势和面积优势,但二者不可兼得,根据实际情况进行取舍,可为现阶段双基地的使用提供理论上的参考,具有一定的军事意义。

Aiming at the problem of simple model in the analysis of effective area of bistatic sonar,this paper puts forward the calculation method of bistatic coverage area under the condition of uneven target intensity,and draws the conclusion of blind area and optimal bistatic configuration.Through the simulation calculation,it is found that the coverage area of the bistatic base changes in a butterfly shape with the change of the submarine course,and the bistatic base has an advantage over a single equivalent base only in a specific area when working.This area is usually referred to as the dominant area,and the baseline distance of the blind area in the dominant area is obtained through the simulation calculation.After the submarine is discovered,it usually escapes within a certain approximate angle.Through the simulation calculation,it is found that the bistatic base has the advantage of distance and area,but the two can not be combined.The choice based on the actual situation can provide theoretical reference for the use of the bistatic base at the present stage,which has certain military significance.
