Modeling and Simulation of Dipping Sonar Active Detection Region

Acoustics environment influences dipping sonar detection sharply,yet former models of acoustics environment effect dipping sonar detection have not concern stereo detection region,which can not set good foundation for anti-submarine searching tactics of dipping sonar.Based on thoroughly analyses and modeling of sound propagation loss,ocean environment noise and reverberation,builds dipping sonar active detection probability model according to sonar detection mechanism,simulates and analyses 3D space distribution of dipping sonar active detection probability,and promotes advise that dipping sonar searching submarine tactics should research uncertainty with new method such as combat experiment with 3D spiccato detection region.
