Abstract

Presented are the results of the continuing study of the statistical properties of the envelope functions of narrowband reverberation. Included are some initial estimations of the intensity spectrum of the reverberation envelope processes generated by scattering 1.0 msec cw signals from the rough, moving surface of a fresh water lake. In addition the intensity spectrum of the time-averaged envelope is estimated. These experimental estimates are compared to the corresponding theoretical quantities derived in earlier research.
