| Abstract: | The PCA based on LOFAR spectrum is one of the most important methods that are used to recognize underwater target.In this paper,the basic principle and specific application process were had analyzed detailedly,then use the real measured noise was used to carry through simulation and classification test,and the simulation diagram and experimental results supplied,which suggested that this method was effective. |
| Keywords: | LOFAR PCA underwater target recognition |
