An algorithm design of a system for the hydroacoustic detection, localization and classification of a suspected at-sea nuclear detonation is presented. Based on basic acoustic principles and nuclear blast theory, the system provides an estimate of the yield-vs-depthaltitude curve for a remote suspect event based on the hydroacoustic signal received at a deep-ocean hydrophone. This system can provide a high-confidence determination of whether or not a suspect atmospheric event is nuclear in origin. A lower level of confidence is placed on the determination of the yield-vs-altitude curve for such an event. The cumulative effect in signal measurement, error in acoustic predictions required by the system, and possible inherent inaccuracies in the method used in determining yield vs altitude could result in order-of-magnitude error in yieldaltitude determinations. Nevertheless, its implementation would provide a valuable adjunct to the present nuclear monitoring system.
