【Abstract】 The spectral characteristics of ship noise is introduced in the paper,and the feasibility of ship target recognition algorithm is studied through the spectrum analysis. Finally DEMON frequency spectrum analysis and axis frequency extraction algorithm have been selected as the implementation of the ship target identification. Taking into account data processing algorithms,hardware platforms and software design based on TI’s DM6446 high performance processor TY-DM6446-1000 development board of the ship target recognition algorithm implementation have been chosen. and the data which based on the experimental algorithm were tested for implementing a statistical. The results shows that the accurate identification of the ship target feature extraction and objectives has been achieved by the algorithm to meet the application requirements.更多还原
