Abstract :
MIMO (multiple-input multiple-output) radar refers to the use of multiple transmitters and receivers, for sensing the environment and the targets present in this environment. Basically MIMO radar uses multiple antennas that transmit correlated or uncorrelated waveforms. For the last ten years MIMO has led to extensive research and publications, both in communications and Radar domains. Why such interest for MIMO in radar? Beside the prolific amount of publications, how to assess the interest of MIMO to overcome the current limitations of conventional radar? The tutorial attempts to answer these questions, as well as to provide the tools to understand the link between theoretical considerations and radar system design. After a summary of the state of art - we may notice that MIMO was invented more than 25 years ago - the course will provide the fundamentals of MIMO radar, how to define a MIMO radar configuration, introduce the signal model, waveform design, signal processing, detection, and localization. A particular emphasis will be put on the coherent MIMO in conjunction with the unique properties of the MIMO steering vector. A large part of the course will be focused on applications, including MIMO-STAP for GMTI, low frequency radar for coastal maritime surveillance.
