Abstract
An experimental method is presented for the estimation of angular and frequency dependencies of the bottom sound reflection coefficient from measurements of the vertical angular spectrum of a natural noise fiel d. A way to increase the accuracy of the method by eliminating the dis tortion of measured noise characteristics, caused by the beam function of the receiver array, is discussed. Measurements of the angular depe ndence of the bottom sound reflection coefficient using a 32-element r eceiver array in various oceanic regions in a frequency band of severa l kHz are presented.
