Abstract :
The application of CDWR for sonar target detection/classification is described. For the detection of targets, the CDWR a time-frequency representation is applied. The selected features are extracted in the CDWR domain. These features are used to train a probabilistic network based classifier to achieve three-way classification of target, no-target and clutter. The experimental details and the results obtained on the data supplied by the US Navy are provided. The target detection results are compared with the detector that is currently being used by the US Navy (NAWCAD). The results indicate that the detector based on CDWR performs better than the algorithm that is currently being used by the US Navy.
