| Abstract: | On the basis of enveloping spectrum analysis of ship-radiated noise, the methods to extracte the features from it are discussed. Then a new method of moveable state recognition has been put forward with founded recognition system. Using this method correct recognition rate for different types of ship targets can be effectively improved, and some of important parameters of target's movement can be obtained at the same time. |
