A Wideband Beamformer Extended to MIMO Radar

Abstract : MIMO radar algorithms are the latest generation of techniques which can be applied to phased array radars. They offer the potential to improve the resolution, number of targets that can be identified, and flexibility in beampattern design. To date, most of the work on MIMO radar has been performed assuming the signals are narrowband. However, wideband signals can also improve radar resolution, among other benefits, and are sometimes unavoidable when stringent range resolution specifications must be met. This paper presents a method for extending the MIMO narrowband model to a wideband model. This is necessary to obtain improved results from parameter estimation when the transmitted signals are wideband. The results show that the method greatly improves the results compared to those obtained when no techniques are implemented to compensate for a wideband signal. However, best performance is still obtained with a narrowband signal, and therefore the technique presented might only be of interest when a wideband signal is required.
