Progress on a testbed for time-modulated arrays

Abstract

This paper discusses the development of a testbed for real-time experimental studies of time-modulated arrays. The proposed architectural design will be described, and the current state of progress will be presented through simulation and over-the-air tests conducted in a lab. The TMA antennas and radios are designed to operate at about 2.3 GHz for a target application of passive radar using XM Radio, in which the TMA capabilities will be targeted at multibeaming and interference suppression.
