基于方位/频率测量的悬浮式深弹炸点控制研究

Research on Explosion Point Control of Hovering Depth Charge Based on Bearing / Frequency Measurement

摘要:

讨论了悬浮式反鱼雷深弹对鱼雷的被动定位与炸点控制方法。 采用矢量水听器检测鱼雷辐射噪声的线谱并测量目标方向,根据高速目标频率与方位变化,通过目标运动分析(TMA)方法预测目标的最近距离。 当该距离小于深弹装药破坏半径时,即发出起爆控制信号,实现炸点控制。 计算机仿真验证了该方法的可行性。

Abstract:

The torpedo’ s passive localization and explosion point control method of anti-torpedo hovering depth charge is discussed. Firstly, the line spectrum of torpedo-radiated noise is detected and the direction of target is located with vector hydro- phone. Secondly, the target motion analysis (TMA) method is adopted to predict the target’s nearest distance based on the frequen- cy and bearing variation of the high speed target. Finally, if the distance is less than the destruction radius of the explosive, the ex- plosion control signal is given to realize explosion point control. Computer simulations validate the effectiveness of the method.
