摘要

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。

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.
