双速制声自导鱼雷主动开机时机研究

Research on Initiative Acoustic Homing Equipment Start-up Opportunity Based on Double-speed Anti-submarine Torpedo

鱼雷主动声自导寻的信号是潜艇探测来袭鱼雷的主要信息源之一,主动声自导开机时机是鱼雷发射时需要设定的重要参数,它直接影响鱼雷攻击的隐蔽性。通过分析双速制鱼雷辐射噪声对潜艇鱼雷报警距离的影响,提出了一种双速制鱼雷直航搜索阶段的变速策略,在此基础上建立了鱼雷主动声自导开机时机解算模型,仿真结果表明,此方法简单高效,结论详实可信,对双速制鱼雷发射诸元解算具有一定的实用价值。

The acoustical signal of torpedo＇s initiative acoustic homing equipment is the prominent source which can be easily detected by the submarine. The start-up opportunity of torpedo＇s homing equipment should be caculated cautiously for torpedo＇s hiding. In this paper,the radiation noise of the double-speed torpedo is analysed and the speed-using policy is presented firstly,then the model of initiative acoutic homing equipment start-up opportunity is simulated based on the influence of torpedo speed on submarine＇s torpedo warring distance and the speed-using tactics in the researching stage,the result shows that this mothod is reasonable and conveniet.
