Evadable optimization model and survival probability analysis of warship with rocket assist acoustic decoy countering torpedo

The evadable maneuvering model of the surface warship with the rocket assist acoustic decoy countering the acoustic homing torpedo and the optimal fire parameter model of the decoy were built up based on nonlinear programming theory. The survival probability of the warship was simulated and analyzed by the models. Some conclusions of launching the decoy were drawn, which can solve the evadable problem of the warship with the decoy countering the torpedo and have important meaning to promoting the employ of the equipment and improving the survival probability of the warship.
