Sonar Pulse Matching Recognition Method Based on Time-Frequency Matrix
The type of sonar pulse is an important source of information for distinguishing targets,and the type of sonar pulse emitted by the target can be used as an important identification feature in target recognition.Therefore,correctly identifying the type of sonar pulse is of great significance.Based on this,a sonar pulse signal matching and recognition method based on time-frequency matrix is proposed,which uses a template matching algorithm based on time-frequency matrix to identify unknown pulse signals in different frequency bands.The simulation analysis results show that this method has higher accuracy compared to traditional methods,can overcome the interference caused by Doppler effect,and can provide a basis for platform target classification and recognition.
