Abstract

The underwater acoustic target recognition based on multi-timeslice demodulation line spectrum feature of radiated-noise is researched. Firstly, the multi-timeslice demodulation line spectrum feature is obtained from the multi-timeslice demodulation spectrum. Secondly, the evaluation method of multi-timeslice demodulation spectrum confusion degree is put forward by using the information entropy. Thirdly, the multi-timeslice target recognition method based on multi-timeslice demodulation line spectrum is researched by using the information entropy evaluation criterion. The comparative result shows that the multi-timeslice target recognition could improve effectively recognition rate of underwater acoustic target.
