Abstract

A new link and energy adaptive UWB-based sensing system is proposed to maximize the detection time coverage of UWB-based pulse radar in embedded sensing applications powered by renewable energy. By jointly considering the link information between the transmitter and receiver of the UWB radar as well as the non-deterministic characteristics of the renewable energy, the proposed system dynamically adjusts the pulse repetition frequency of the UWB radar to enhance the energy efficiency. Simulation results demonstrate that the proposed system can significantly improve the average detection time coverage as compared with the conventional system. The proposed technique is also insensitive to battery issues such as limited battery capacity.
