Bionic communication detection method based on prolate spheroidal wave function

The invention relates to a bionic communication detection method based on a prolate spheroidal wave function, and relates to the prolate spheroidal wave function. The method comprises the steps of (1) utilizing the prolate spheroidal wave function (PSWF) and various-order functions as primary functions for fitting a dolphin communication signal; (2) extracting a waveform envelope of the dolphin communication signal and calculating extreme points of the waveform envelope; (3) extracting a waveform between the extreme points; (4) constructing multiple prolate spheroidal wave functions and carrying out weighted fitting; (5) determining a prolate spheroidal wave function combining function and a related function of the extreme point waveform, and obtaining an extreme value; (6) giving an iteration value, and repetitively calculating the step (4) and (5) until obtaining a suitable weighted value of an impulse function group.
