The Range-Dependent Active System Performance Prediction Model (RASP)

Abstract:

In 1984, the Naval Research Laboratory NRL published a report that described a sequence of computer programs to predict long-range, low-frequency monostatic or bistatic reverberation for either the ocean surface or bottom. Since that time, numerous improvements and extensions have been made to the original sequence of programs that have incorporated advances in the theory and understanding of underwater acoustics, numerical modeling, and computer software. Examples of enhancements include the addition of predicted target returns, improved spatial interpolations of sound speed, and the application of a wave-theoretic treatment of caustics. The present collective versions of the programs is now referred to as the Range-dependent Active System Performance, or RASP model. This report presents the theoretical foundations of the RASP model as well as the numerical implementation of this theory. Further, a detailed description of model software and instructions for model execution are provided along with the results of a sample execution.
