摘　　要：考察远程双基地界面混响,可以仅考察二维问题,其散射区域为一椭圆环带;对于近程双基地界面混响,必须讨论三维模型,其散射元分布在一椭球面上.对二维和三维双基地混响进行理论建模分析,该模型优点是无需使用无线电通信,借助GPS时钟即可同步工作,实现双基地声呐系统的测距及测向,便于双基地声呐系统的集成.推导出二维和三维模型的双基地声压混响理论预报公式.对三维矢量混响作仿真研究,并讨论矢量传感器组合指向性抗混响.In researching long-distance interface bistatic reverberation, the scattering area is taken as an elliptical ring. In researching short-distance bistatic reverberation, the model should be a three-dimensional ellipsoid. The ellipse and ellipsoid models can work without wireless communication, only using GPS clock to make sure the systems work synchronously so as to realize ranging and orienting. It is convenient for the integration of bistatic sonar system. The two-dimensional and three-dimensional prediction formulas of bistatic pressure reverberation are deduced, the vector-sensor three-dimensional reverberation is simulated and the anti-reverberation performance of vector-sensor directivity composite is discussed.
