Persistent Sensing with Impedance-Matched Energy Converters
Abstract
Persistent Sensing with Impedance-Matched Energy Converters. The focus of the base period is on hydrodynamic modeling of the overall dynamics involving asubmerged object, irregular waves passing over it, and an impedance-matched detector/array located a few wavelengths down-wave of the submerged object. For the purpose of defining this measure, swell conditions are assumed. Experimental testing in a small wave tank is proposed for year II, and will be pursued subject to attaining or exceeding the threshold performance expectations.JHU will quantify the performance limits of a persistent non-acoustic approachto detection of submerged objects. The approach is a hidden by-product of the real-time impedance matching technique used to optimize energy conversion from irregular ocean surface waves. The amounts of time-averaged power generated by small bodies under control can exceed hundreds ofwatts, and would be available for maritime applications requiring persistent sensing. However, the object of the proposed research is the detection of submerged bodies is the use of such control for the detection of submerged bodies. In particular, the goal is to obtain a quantitative figure of merit forthe proposed approach to submerged object detection.
