摘要
On the basis of envelope spectrum analysis of ship-radiated noise, the features and the extracting methods are discussed, and then a new method of dynamic recognition has been proposed. Using this method, accurate recognition rate for different types of ship targets can be effectively improved, and some of the important parameters of target＇s movement can be obtained at the same time.
