Airborne Ocean Acoustic Measurements: Determination of Explosive Source to Sonobuoy Spacing,
Abstract
This center has conducted propagation loss measurements of sound in the ocean using sonobuoys and small explosive charges dropped from aircraft. Translating the data recorded from the buoys into propagation and bottom reflectivity information requires accurate knowledge of the ranges form each explosion to the buoys. Two methods for finding these ranges are: (1) to predict the impact points of the stores from their trajectories after launch from the the aircraft; and (2) to compute the range from the time spacing of the various energy arrivals from the explosions. This report compares these two methods and investigates the weaknesses of each in an attempt to select the most suitable one for NAVAIRDEVCEN tests.
