Retrodirective technologies for Terrestrial Sensor Networks

Abstract

This thesis focuses on the development of retrodirective technologies for remote intelligence-gathering sensor networks. The directivity and autonomous beam-steering capabilities of retrodirective arrays make them attractive candidates for networks operating in hostile environments where covertness is a necessity. Two arrays are described: a self-phasing receive array for BE sensing and tracking, and a full-duplex, two-dimensional retrodirective array based on phase detecting and heterodyne scanning for communicating between the sensor and a collection vehicle. The arrays were designed, tested, and characterized and show promise for use in the proposed application.
