Abstract: The detection ability of submarine is the prerequisite to obtain the operational advantage in the actual combat. Acoustic detection, as the most important sensing detection means of submarine, is closely related to submarine attitude, relative position, combat behavior and environment. Static acoustic detection index dose not meet the requirements for exercise evaluation. Starting from the relationship between submarine motion and sonar detection capability in actual combat, the composite function of submarine motion equation and sonar mechanism equation based on the engagement process is constructed, an acoustic perception interaction mechanism equation is established according to the relationship between them, and then the case verification is made with the navigation test data. The behavior mechanism equation reveals the law of sonar detection ability changing with submarine attitude, space position, speed and other motion variables, which provides the basis for obtaining and utilizing the detection advantages by changing submarine motion state in actual combat, and is conducive to obtain the combat opportunity for the game between friend and foe in the stage of search and perception.
