Abstract
Using the spectral solution to the evolutionary Burgers equation, we have numerically simulated the propagation of intense random acoustic waves in a nondisperse medium. We have solved the problem of reconstructing the initial signal spectrum using the measured spectral and bispectral characteristics of the received signal on short tracks.
