Lou Greene, Sherrell The Nuclear Electric Vehicle Optimization Toolset (NEVOT) optimizes the design of all major nuclear electric propulsion (NEP) vehicle subsystems for a defined mission within constraints and optimization parameters chosen by a user. The techniques for software control of the sonar parameters were explained followed by the details of the realization of the sonar functions and some discussion of the performance of the side scan sonars. The software documentation is the SST Web (a large HTML 'web site' distributed with the SST software), supported by a collection of documented examples. A command language controls a large collection of component models describing the ocean, sonars, noise sources, targets, and signals. Eigenrays from the Generic Sonar Model (GSM) or the Comprehensive Acoustic System Simulation (CASS) can be used, making all of GSM's propagation models and CASS's Gaussian Ray Bundle (GRAB) propagation model available to the SST user.
Externally generated or measured signals can be added to the output signal or used as transmissions. SST's simulated signals include reverberation, target echoes, discrete sound sources, and background noise with specified spectra. 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.
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.
