A review on Multiple-input multiple-output (MIMO) radar is given that is with widely separated antennas. MIMO radar is an architecture that employs multiple, spatially distributed transmitters and receivers and is even considered as a multistatic radar. The spatial diversity of the target's radar cross section (RCS) is being captured by these widely separated transmit/receive antennas. Explanations and some illustrations of the unique features of MIMO radar are given. A target's RCS spatial variations can be utilized with noncoherent processing to obtain a diversity gain for target detection and for the estimation of various parameters. Furthermore, coherent processing can provide a resolution that is far better than the ones supported by the radar's waveform.
