A Curve Fitting Technique for Acoustic Ray Analysis

摘要

The report describes a mathematical technique for approximating a velocity-depth profile with a segmented curve having continuous first derivatives. Each segment is represented by a function that permits the range integral to be evaluated in closed form. The technique was incorporated into a computer program that determines the function parameters and provides a digital plotter tape. Thus, the smoothed velocity-depth profile curves and the input data can be qualitatively compared. (Author)
