A Study on the Modeling and Simulation of On-called Anti-submarine of ASW Helicopter by Using Dipping Sonar

Based on the detection theory of ASW helicopter'dipping sonar and its characteristic,a scatter model for searching submarine is built on the condition of the known submarine initial location and the unknown course and speed of submarine,and then deduces dipping sonar's searching efficiency formula,and build searching efficiency model of dipping sonar by round or square searching shapes according to the regular scatter pattern of the submarine. Simulation analyzes the searching efficiency by using dipping sonar on the condition of the known submarine initial location and the unknown course and speed of submarine is based on Monte Carlo Method. It proves that the results of searching probability is almost the same to the searching algorithm through the tests of dipping sonar in different times,which gets the result that it is effective to the use of searching efficiency model and also analyzes the influence of the varieties of searching range of dipping sonar versus searching efficiency.
