Documentation of a Computer Code by HKC Research to Calculate the Transmission of a Sonic Boom Through a Wavy Ocean Surface
Abstract
A "sonic boom wavy surface" computer code was developed by HKC Research at the University of Southern California (USC) over the last few years. It was distributed in April 2003 via CD through PARSONS, Pasadena, to the Air Force. A final report was also distributed. The problem addressed by this code is that of a sonic boom passing over a wavy ocean surface. The pressure wave transmitted through the wavy interface is the primary output of this code. The theory upon which this code is based is presented in a USC Report authored by H. K. Cheng and C. J. Lee. The purpose of the current report is to document the code by explaining the calculations performed therein, and placing the numerical routines in correspondence with the equations which appear in the USC Report. Code results from a sample input set are also presented in order to provide a benchmark for future users and against which to compare possible future releases of this code by Cheng and Lee. The emphasis of this report is on code documentation. No assessment nor interpretation of the theory is offered. Although the Cheng and Lee code is not currently in standard use for predicting sonic boom transmission into the ocean, this document may hasten its adoption as a standard tool for this purpose.
