Recent advances in the technologies associated with phased array apertures, digital waveform generators, and signal processing have enabled a broad class of Multiple-Input Multiple-Output (MIMO) radar techniques. In the last decade and a half, the MIMO radar nomenclature has been applied to various signaling and processing techniques that employ multiple, independent radiating transmitter elements that work cooperatively with multiple, independent receiver elements. This tutorial is intended to provide an overview of the principles of MIMO radar with an emphasis on applications and beamforming techniques for phased array radar systems.

First, this tutorial will briefly review the history of developments in the fields of radar, communication and control theory that led to the emergence of the “MIMO radar” taxonomy in the early 2000’s. An overview of MIMO radar will be provided covering the broad class of MIMO-enabling waveforms, comparisons with traditional single-input radar systems, and the various canonical forms of MIMO radar in the published literature. Second, this course will expand upon waveform design approaches for MIMO radars. A coherent MIMO radar signal model will be presented that illustrates the utility of spatio-temporal signal processing for phased array systems – including a posteriori transmit beamforming. Then, performance of MIMO radar systems will be explored in the areas of parameter estimation, track and search rates, and requirements and cost for hardware implementations. Finally, several examples of MIMO radar operation will be presented spanning pulsed-Doppler, airborne GMTI, and high frequency over-the-horizon radar applications.
