Title: Methodology for Yield Determination of Surface Shots Over Water

Abstract

Shockwave analysis is one of the few methods used to determine the yield of a nuclear detonation. It has been noted that the shockwave of these surface shots over water are asymmetric making accurate yield determination difficult. To calculate the yield of these shots more accurately, reanalysis of these films is required. Armed with the digitized replicas of the original nuclear test films and the latest image processing tools, a methodology for segmenting the shockwave from the digitized film and measuring these shockwaves is devised to quickly and accurately quantify the shape of these asymmetric shockwaves. With a two-dimensional result from these asymmetric shockwaves, several methods are discussed to transform the final shockwave contour to a scalar value which can be used in existing yield determination equations.
