声自导鱼雷二次转角作战使用方法

Operational Application Method of Two-time Turning Angle for Acoustic Homing Torpedo

针对声自导鱼雷在一次转角作战方式下,存在鱼雷与目标相遇时目标多普勒速度未能达到自导检测阈值导致难以检测到目标的情况,从目标多普勒速度与鱼雷自导检测阈值分析入手,提出满足鱼雷自导检测的二次转角作战方式,并建立模型。通过蒙特卡洛法求解声自导鱼雷在一次转角作战方式和改进后二次转角作战方式下的发现概率,并考虑目标机动的情况。结果表明,改进后的二次转角作战方式可提高声自导鱼雷的发现概率。

In the case of one-time turning angle operation mode of an acoustic homing torpedo,the Doppler velocity of the target does not reach the threshold of homing detection threshold as the torpedo is meeting the target,which leads to difficulty in detecting the target.This paper analyzes the target Doppler velocity and the torpedo homing detection threshold,then puts forward a two-time turning angle operation mode to satisfy torpedo homing detection,and establishes a model.The detection probabilities of an acoustic homing torpedo in one-time turning angle operation mode and improved two-time turning angle operation mode are solved by Monte Carlo method with consideration of target maneuvering.The results show that the improved two-time turning angle operation mode can improve the detection probability of an acoustic homing torpedo.
