Simulative Research on Responding-antisubmarine of ASW Helicopter Which Using Dipping-sonar

Responding-antisubmarine is one of major antisubmarine method of ASW helicopter which using dipping sonar. In the base of analyzing the dipping sonar responding-antisubmarine search process, carrying on the simulation environment, building the MonteCalo model of dipping sonar, study the dipping sonar coefficient at interval, spiral coefficient, the checked number of detection, and search formation. By way of studying, no matter single or double helicopter, it’s better to use helix battle array and spiral coefficient is taken 0.6 and 0.7 respectively.
