Ship Evasive Strategy while Releasing Suspended Depth Charge Against Acoustic Homing Torpedo

Evasive maneuver is one of key problems a surface ship faces while releasing suspended depth charge to intercept a torpedo. This paper analyzes the process of depth charge intercepting torpedo, establishes a model of ship evading acoustic homing torpedo, and obtains the evasive turning angle as evading torpedo in different torpedo alert areas by using Monte-Carlo method. Simulation result shows that expectant evasive probability can be achieved with non-evasion or small angle evasion under the cover of suspended depth charge array.
