Abstract
A method is described for measuring the amplitude-frequency and spatia l (directional) characteristics of underwater acoustic arrays in real environments, i.e., in the presence of interfering reflections. The me thod is based on the application of time-delay spectrometry and wideba nd swept-frequency signals. The results of full-scale experiments are reported, demonstrating the high accuracy, noise immunity, and efficie ncy of the proposed method.
