| Abstract: | 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. |
