摘要
目标识别技术是武器精确制导的前沿课题，是高新技术领域的核心机密。本文在调查国内外鱼雷关于目标识别技术研究成果的基础上，较详细地介绍了该技术的研究和应用现状，展望今后的发展方向，可供水声界同行参考。
Target discrimination techniques are the leading task and the key secret in this new technical field. In this paper the applications of target discrimination techniques to torpedo and sonar system in the world are introduced. The developing trend of the techniques is also discussed. Key Words: torpedo; target discrimination; underwater sound countermeasure.gleton and 25 doubleton,respectively accounting for 24.9% and 14.1% of the total species number,are identified in the plots.These species with a low density and small population are more declined to extinct than the dominant species under any disturbance.The loss of the singleton and doubleton species will lead to a low species diversity in the community.
