Measurement of the Acoustic Impedance of the Ocean Bottom.

Abstract

Transducer circuit theory is used to derive a means for measuring the impedance of a locally reacting surface. A directional source, linear or parametric, insonifies a finite area in a reference plane at which the impedance is specified. Computer programs are referenced for calculating the required diffraction constants and radiation impedance for the test geometry. (Author)
