Abstract

This article presents formulas to calculate the source depth based on the arrival angle and time delay between the direct and surface-refracted arrivals measured in deep water from a broadband signal. Using the formulas, the data autocorrelation is transformed to a correlation sequence as a function of assumed source depth, which can be simply averaged over a long time to estimate the source depth in a noisy environment. Both the simulated and real data verify the effectiveness and efficiency of the proposed method.
