Abstract:

This document consists of the text and slides of an invited paper presented at the 108th Meeting of the Acoustical Society of America, held in Minneapolis, Minnesota, from 8 to 12 October 1984. The following abstract was published in the program for the 108th Meeting J. Acoust. Soc. Am., Supplement 1, Vol. 76, Fall 1984. By the mid-1970s, the use of wavevector-frequency spectral analysis as a diagnostic tool for structural-acoustics had been theoretically and experimentally demonstrated. In anticipation of a continuing need for this diagnostic capability, we decided to develop a wavevector-frequency spectral analysis system suitable for general application in spatially planar fields. This paper outlines the development of that prototype system, from theory to hardware. Emphasis is focused on the practical aspects of the development and the consequence of design decisions. Data from a simple, but practical, application of the system are presented and discussed.
