METHOD AND APPARATUS FOR DETECTION AND CLASSIFICATION OF A SWIMMING OBJECT

摘要

A method and apparatus for detection and classification of submerged swimming object from a passive signal generated by the object and an active signal reflected from the object. In an first input of a passive mode branchv a first signal representative of the passive signal is received. A second signal representative of the active signal is received in a second input of an active mode branch. In the active mode branch, the first signal is processed to generate a first classification estimate output, with first clues, of the most probable class of target for the object. In the passive mode branch, the second signal is processed to generate a second classification estimate output, with first clues, of the most probable class of target for the object.The first and second estimate outputs are received in a merger, for generating a merged classification estimate output with clues, whic is input to a joint classifier tha classifies the object by performing joint classification based on said a merged classification estimate output with clues.
