Abstract:

The Sonar Simulation Toolset SST is a computer program that produces simulated sonar signals, enabling users to build an artificial ocean that sounds like a real ocean. Such signals are useful for designing new sonar systems, testing existing sonars, predicting performance, developing tactics, training operators and officers, planning experiments, and interpreting measurements. SSTs simulated signals include reverberation, target echoes, discrete sound sources, and background noise with specified spectra. Externally generated or measured signals can be added to the output signal or used as transmissions. Eigenrays from the Generic Sonar Model GSM or the Comprehensive Acoustic System Simulation CASS can be used, making all of GSMs propagation models and CASSs Gaussian Ray Bundle GRAB propagation model available to the SST user. A command language controls a large collection of component models describing the ocean, sonars, noise sources, targets, and signals. The software documentation is the SST Web a large HTML web site distributed with the SST software, supported by a collection of documented examples. This report emphasizes the science, mathematics, and algorithms underlying SST. It is intended to be updated often and distributed with each release of SST as an integral part of the SST documentation.
