摘要
舰艇速度的变化会引起舰艇辐射噪声声源级的变化 ,从而改变鱼雷对目标的被动自导作用距离。本文根据声纳方程 ,从能量检测的角度分析了舰艇以常速和高速规避时 ,被动自导鱼雷发现目标的概率。进一步用对抗过程仿真的方法研究了规避速度对舰艇生存概率的影响。计算结果表明 ,在一定报警区域 ,舰艇以常数规避优于加速规避。
The noise energy radiated from a ship will change with the ship's velocity. Based on the energy change, the acquisition range of a passive homing torpedo will change also. The probability of passive homing torpedo to find a vessel running in the velocity of 18kn and 30kn is respectively estimated from the point view of energy detection based on sonar equation in this paper. Furthermore, effects of the evasion velocity on the survival probability of a vessel were studied by simulating the countermeasure process. Calculation results show that the range of acquisition of passive homing torpedo to a vessel running at its maximum velocity will be higher than that running in usual velocity under the same conditions. The survival probability is higher in normal evasion velocity than in speeded velocity in some alarm areas.
