摘要
简述了水雷隐身技术的发展现状,指出声呐是探雷技术发展的主要手段和方向。根据猎雷声呐探测识别方式,提出降低目标强度、减弱甚至消除声影是实现水雷武器声隐身的主要技术途径,并从这2个方面分析了水雷隐身对猎雷声呐探测识别效能的影响。其中,当采用回波法探测识别水雷时,水雷目标强度的降低可缩短声呐的探测距离,并且在清澈海水中其效果较好;而对于声影法探测识别,则需要消除或减弱水雷的声影才能使其难以被猎雷声呐发现。
In this paper,we concisely introduce the state of stealth mine technology and point out that sonar is the chief way of sea mine detection. According to the method of detection and classification used in mine-hunting sonar,target strength and acoustic shadow are two main acoustic features of sea mine. So, monishing these two acoustic features is an effective way to sea mine stealth. Then, we analyze the influences on mine hunting sonar from the above two aspects. The result shows that, when we search sea mine with the sonar echo, the decreasing of target strength can short the detecting distance of sonar, and the effect in clear water is much better than that in muddy water. When we detect a sea mine by its acoustic shadow, we must diminish or eliminate the acoustic shadow to make it concealed from mine hunting sonar.
