Abstract:

The warning sector, demand of force and parameter decisions in helicopter antisubmarine search for threat from stern of ship formation with dipping sonar are investigated. The process of antisubmarine search with dipping sonar and the features of saw-tooth method are analyzed. A quantitative model for warning sector is built for multiple helicopters antisubmarine search at stern of ship formation. The influencing factors of saw-tooth method are analyzed, such as search velocity, and the spacing coefficient of adjacent detecting points. The relationship between submarine velocity and detection range of dipping sonar is investigated. The method for calculating equivalent circle radius of the detected area is provided. The actual warning sector against submarine, the optimum spacing coefficient, and the force demand when antisubmarine helicopters search the stern of ship formation using dipping sonar are simulated. Results show that deploying 2 helicopters to 15 n miles at the stern of ship formation could cover warning sector of 80.9°, and the optimum spacing coefficient is between 1.1 and 1.3.

Key words: antisubmarine search at stern of ship formation, saw-tooth method, warning sector against submarine, dipping sonar, antisubmarine helicopter, following submarine
