| Abstract: | Detecting and locating acoustic fault is an important process to maintain the stealthy of the warship,an expert system using case-based reasoning was developed to carry it out.D-S theory was introduced to fuse the information obtained through the process of case-based reasoning.A method based on euclidean distance between the samples to establish the mass function,which was difficult to obtain,was proposed.The experiment proved that the method is feasible. |
