Underwater Acoustic Target Recognition Based on Multi-timeslice Demodulation Line Spectrum Feature

摘要：

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.
