Abstract

In view of principle of biomimetic technology, feature extraction from acoustic targets can influence the performance of whole system to enhance recognition performance. Several kinds of time domain, frequency domain and cepstrum domain were researched, including linear prediction cepstrum coefficient, mel-frequency cepstrum coefficient (MFCC), dynamic acoustic feature and wavelet feature and etc. The recognition results of components of different feature for acoustic target system were given. The results show that recognition rate based on MFCC is higher than others reaching 96.8% under different object.

Key words： biomimetic technology; acoustic feature; target recognition
