The combat target of ATT is torpedo,which is characterized by low target intensity,fast speed,complex and changeable ballistics.Therefore,ATT homing system must have the capability of small target detection,high target information data rate and fast self-adaptation,target recognition.This paper analyzes the different characteristics of the information between torpedo and other underwater targets,and determines the characteristic to be extracted from target recognition.At the same time,the LDA algorithm of intra-class weighting is used to identify the target.
