Low-power Radar for Wireless Sensor Networks

This paper presents the results of a short study on the feasibility of radars as the primary means of sensing in ad-hoc wireless sensor networks. Radar offers distinct advantages over others means of sensing, normally found in this kind of networks. The sensor networks being considered consist of battery powered nodes. Hence, power consumption is of prime importance. A simple detector front-end has been built to serve as a proof of concept and to verify performance metrics such as power consumption and detection range. The results clearly indicate radar as a suitable sensor for wireless sensor networks
