Function:

This multi-threaded MOOS module works in concert with the Virtual Ocean environmental acoustic modeling modules in a nested simulation framework to generate real-time, element-level timeseries for arbitrary hydrophone and vector sensor array configurations on fixed or mobile active sonar platforms, 'operating' in a 4D NetCdf virtual representation of the ocean environment. The simulated array response includes surface generated ambient noise and sea-state dependent reverberation through realizations of a legacy reverberation statistic model. It supports arbitrary distributions of dynamic acoustic targets with aspect-dependent scattering characteristics. The sonar source is azimuthally isotropic with vertical directionality, i.e. equivalent to a shaded vertical source array. Supports mono- and bi-static configurations.
