Paper Abstract

Technology for the detection of enemies from behind barriers and for securing of ports and perimeters with minimal threat to warfighters is essential in modern threat scenarios. We are developing a network of small scattered Doppler radar sensors which lie in wait and report on change or motion within a targeted perimeter. Most sensors are simple radar receiver "nodes" capable of short range communications and long operation life with minimal power requirements, while a few are more advanced radar transceiver "beacons" capable of active interrogation and long range communications. Radar nodes and beacons could be scatter-deployed from a distance, creating a need for post-deployment localization in order to provide useful reconnaissance. A beacon is designed to have absolute position knowledge by strategic deployment of GPS, produces an interrogation signal, and analyzes locally received echoes for signs of motion activity in the targeted area. Scattered nodes in the targeted vicinity form an ad-hoc network which also receives and compares the beacon signal and its target echoes, and reports sensed activity to the beacon. This paper introduces such a system and discusses radar node localization based on signal strength using kernel methods and distributed learning algorithms which take energy constraints into account.
