On Wideband MIMO Radar : Extended Signal Model and Spectral Beampattern Design

Abstract : MIMO radar systems can increase the radar resolution, the number of targets that can be identified, and the flexibility in beampattern design in comparison with standard phased array radars. To date, most of the work on MIMO radar has been performed assuming the signals are narrowband. However, wideband signals can improve radar resolution, among other benefits, and are sometimes unavoidable when stringent range resolution specifications must be met. In this paper, we present a method for extending the MIMO narrowband model to a wideband model. Next, from the exact expression of the spatial power distribution involving the CSDM (Cross-Spectral power Density Matrix), we propose a suboptimal transmit beampattern synthesis technique, which can be used in the context of wideband signals.
