Research and analysis on military strength demand of dipping sonar on-call submarine searching based on submarine evasion

Based on the actual process of dipping sonar in on-call submarine searching, combined with the classic extended spiral search method, a multi machine dipping sonar on-call submarine searching model was established. A submarine motion model was built based on the possible avoidance measures that submarines may take during the on-call submarine searching. We calculate the variation of detection probability of suspended sonar with response time and response distance of dipping sonar. Moreover, we also analyze the military force requirements of dipping sonar for submarine search under different response time and response distance of dipping sonar. So the obtained relevant conclusions can provide theoretical basis for tactical decision-making of anti-submarine helicopter response submarine search.
