Environmental Sensor Simulation System

"The objective of this research is to produce an environmental sensor simulation system (ESSS) that will support advanced research and development for ASW. Efforts are underway to design new environmental sensors that will enable accurate, timelymeasurement of the ocean environment, especially for the shallow littoral regions where the environment is highly variable in time and space. One such sensor, the Tactical Acoustic Measurement and Decision Aid (TAMDA) will provide measurements oftemperature, ambient noise, and bottom properties through active pulse inversion, for Air ASW systems in a manner that is tactically relevant. This research will support TAMDA and other sensor programs by providing an environmental simulation environmentthat provides a high degree of fidelity and resolution temporally, spatially and azimuthally. AHA's approach includes the specification of the basic functional, operational, and infrastructure segments that comprise the system. A detailed designspecification of each functional segment will then be provided, based on AHA's significant prior experience in environmental simulation and environmental sensor design requirements analysis. Finally, AHA will produce a basic functioning prototype, using acomponent-based development paradigm for demonstration during the first phase. The potential benefits of this advanced environmental simulation research, are significant. First, Navy environmental sensors s
