摘　　要：为了验证水声干扰子弹水下爆炸声信号对抗声自导鱼雷的效果,基于水下爆炸的声信号具有声源级高、覆盖频率宽的特点,建立了水声对抗数学模型,并应用数学优化方法,将对抗问题转化为非线性有约束的目标优化函数,得到了舰艇最佳规避角和干扰弹最佳落点位置,且发现最佳发射角度变化较小。仿真结果表明,水声干扰子弹在最佳发射条件下,能有效干扰声自导鱼雷。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.
