| Abstract: | This paper presents the results obtained in the model experiments on the remote measuring of the acoustic impedance profile of a sea-bottom consisting of horizontal layers. The experiments were conducted in the cooling-water pool of a paint factory. Three inverse methods were used for the sound signals from a three-medium layer system. While the error by the difference method increased dramatically, leading to overflow in computation, and the results given by the "sample iteration" method was irrational, the results obtained by using the "sample-averaging iteration" method were quite close to the measured acoustic impedance. |
