Abstract
The present invention relates to the technical field of bionic covert underwater acoustic communication, and specifically relates to a feature extraction-based imitated marine mammal sound signal covertness scoring method. The scoring method combines feature engineering to extract six universal features of a marine mammal sound signal from the perspective of human hearing and a signal waveform, and uses these features to obtain a second bionic signal covertness score through a weight coefficient formula. The covertness scoring method can characterize intrinsic information of the bionic signal in more detail from more perspectives of the signal to more accurately evaluate a difference between the bionic signal and a real signal, and the obtained score value can more intuitively describe the quality of the bionic signal covertness.
