中文摘要:
      鱼雷防御是从对来袭鱼雷的识别报警开始的, 所有鱼雷防御系统的基础是其对鱼雷的检测、分类和定位能力。为了有效地对抗鱼雷攻击, 各国海军正在努力提升其声纳的鱼雷目标检测、定位和识别性能。文章对国外鱼雷报警系统的现状和发展趋势进行了分析和评述。鱼雷报警功能可以利用专门的鱼雷报警声纳来实现, 也可以集成在一个被动拖线阵里。但通常由一个主被动联合拖曳阵声纳和舰壳声纳构成一个完整的系统, 共同完成鱼雷辐射噪声的被动检测、分类和主动回波信号的分析, 每个声纳都为鱼雷这个高速小目标的检测定位进行了优化。这样的系统由于可以采用基元数众多长线阵、更好地利用声场条件等, 可以实现对鱼雷目标的远距离识别、定位和全方位覆盖。系统部分组成通常也是反潜战能力的组成部分, 而将鱼雷检测和水声对抗结合正成为一种新的发展趋势, 一些拖曳阵可以作为软杀伤对抗措施欺骗其检测到的鱼雷目标。
英文摘要:
      Torpedo defence begins with the recognition and warning of incoming attack torpedo. The foundation of all torpedo defence systems is the detection, classification and localization (DCL) capability. Great efforts are being made to improve sonar performance of torpedo DCL to protect their ships from the growing underwater threats for navies worldwide. The status quo and development trend of torpedo warning system are discussed and surveyed in this paper. Torpedo alert function can be provided by dedicated intercept sonar or integrated into a passive sonar array. This usually consists of towed arrays and hull-mounted sonar to detect the propulsion and/or homing signals from the threatening torpedo, and high-tech signal processing and analysis systems to confirm the nature of the threat and determine direction of approach, each of them is designed to be appropriate to the DCL of torpedo. Such systems provide long range classification and localization capabilities and 360° coverage due to the long array with more hydrophones and the best use of sound conditions. Frequently, some parts of the DCL system also are components of a ship's ASW capabilities. Some anti-torpedo towed array sensors also serve as countermeasures to deceive the threat they detect, which shows that the combination of torpedo detection and countermeasure is a development trend.
