    Abstract
  • Acoustic interference ammunition is a kind of new concept munitions. To verify its effect of underwater explosion signal on acoustic homing torpedo, we establish an acoustic countermeasure model by making use of the features of high source-level and wide bandwidth of the signal for a ship to evade acoustic homing torpedo, and translate countermeasure problem into a nonlinear and constrained target optimization function by mathematical optimization methods. As a result, the optimal evasion angle and the perfect location of acoustic interference ammunition are obtained, and smaller variation of opti-mal launch angle is achieved. Simulation results show that acoustic interference ammunition can interfere acoustic homing torpedo effectively under optimal launching condition.
