This tutorial will explain MIMO radar from an easy to understand physical point of view rather than with heavy exoteric math. It is shown how a conventional radar using the same arrays as the MIMO radar can yield the same advantages as claimed for MIMO radars. Specifically it is shown how the conventional radar can provide the same orders of magnitude resolution and accuracy as claimed for MIMO radars. It can do this using the same search time and about the same power-aperture product. The properties of the full/thin MIMO and conventional array radars are detailed relative to waveforms and matched filter signal processing loads. The matched filter processing load for MIMO radars are dependent on whether the transmit or receive beam forming is done first. Using easy to understand Cognitive Adaptive Array Processing (CAAP) it is shown that MIMO radar systems do not have any advantage relative to barrage, hot-clutter or repeater jammer suppression. It is shown how the MIMO thin/full array used for GMTI in airborne radars to obtain improved detection of slow moving targets can also be used to provide the same minimum detectable velocity improvement when used in a conventional array radar. The wide use of MIMO radar in automobile radars will be elaborated on. Other potential applications for MIMO radars to be discussed are for OTH and the combining of existing radars, like two, for increased sensitivity of 9 dB.
Dr. Eli Brookner is well known for his contributions to radar technology. He retired from Raytheon as Principal Engineering Fellow in 2014 after a long and distinguished career. He has contributed to radars for air traffic control, defense, space and navigation – virtually every major defense radar program. Eli has been recognized with numerous awards and honors, including Fellow of the IEEE, AIAA, and MSS and the 2006 IEEE Dennis J. Picard Medal for Radar Technology and Application and the 2003 IEEE Warren White Award. He has written numerous papers and articles and four books on radar systems, phased arrays and tracking. Eli received his bachelor’s degree in electrical engineering from the City College of New York and his master’s and Dr.Sc. from Columbia University.
