MIMO Radar


Date: May 11, 2011
Time: 8:00am - 12:00pm
Instructor: Mike Davis, Bill Melvin

Tutorial Code: T-13


A MIMO system is one that uses a number of transmitters ("multiple-inputs") and a number of receivers ("multiple-outputs") in order to significantly improve performance when compared to its single-input, single- output (SISO) counterparts. MIMO techniques have lead to dramatic improvements in wireless communications, which have inspired radar researchers to study similar concepts. This tutorial will describe how MIMO techniques can improve radar performance and provide the student with an in-depth understanding of how these performance gains are realized and what is required to provide them.


The primary goal of this tutorial is to present a framework for assessing the utility of MIMO techniques for a particular radar application. The student will be presented with a review of MIMO radar research, which will be placed into the context of the current state of the art of radar technology. After this course, students should be able to evaluate claims of MIMO radar and to have an understanding of how MIMO can and cannot improve radar systems.

Potential Students

This tutorial is aimed at researchers, developers, and users of radar systems who are interested in understanding how MIMO and other technologies will impact radars of the future. A familiarity with array processing concepts will be valuable for understanding the details of the theoretical development, but a basic knowledge of radar systems will be sufficient to follow the discussion.


The tutorial will be four hours and is divided into four lectures.

  1. An Overview of MIMO Radar (Melvin - 60 minutes) The term MIMO radar is relatively new, but this concept has built upon several decades of radar research. This lecture will discuss how MIMO radars relate to existing systems and provide the appropriate context.
  2. MIMO Communications (Davis - 60 minutes) MIMO techniques first gained attention for revolutionizing wireless communications. In an attempt to capitalize on the pervading similarities between communications and radar systems, radar researchers sought 1 to apply these techniques to their system. This lecture will discuss these similarities to illuminate connections between MIMO communications and MIMO radar.
  3. MIMO Radar: System Modeling and Performance Analysis (Davis - 60 minutes) In a sense, a MIMO radar is simply a generalization of the phased array antenna architecture that has been employed by radars for decades. This lecture describes how a MIMO radar can be characterized by the correlation among its transmitted waveforms and how this relates to system performance.
  4. MIMO Radar Applications (Showman - 60 minutes) A survey of proposed applications for MIMO techniques to radar systems will be presented. Topics will include ground-moving target indication (GMTI) radar, synthetic aperture radar (SAR) imaging systems, over-the-horizon radar (OTHR), as well as other operating modes that may be potentially enhanced by MIMO. Common threads connecting scenarios where MIMO can substantially improve radar performance will be identified.

Instructor Biography

Mail Mr. Mike Davis has been employed at the Georgia Tech Research Institute since 2008, where he conducts research in the area of radar signal processing with a focus on adaptive algorithms for radar imaging, moving target indication, and electronic warfare. Before this, he was with General Dynamics, formerly known as the Environmental Research Institute of Michigan (ERIM). Mr. Davis earned a B.S. in computer engineering from the Rose-Hulman Institute of Technology in 2003 and a M.S. in electrical engineering with an emphasis in signal processing from the University of Michigan in 2007.

Dr. Bill Melvin is Director of the Sensors and Electromagnetic Applications Laboratory (SEAL) at the Georgia Tech Research Institute and an Adjunct Professor in Georgia Tech's Electrical and Computer Engineering Department. His specific expertise includes digital signal processing with application to RF sensors, including adaptive signal processing for aerospace radar detection of airborne and ground moving targets, radar applications of detection and estimation theory, electronic protection, SIGINT, and synthetic aperture radar. He has authored over 150 publications in his areas of expertise and holds three patents on adaptive radar technology. Dr. Melvin received the Ph.D. in Electrical Engineering from Lehigh University in 1994, as well as the MSEE and BSEE degrees (with high honors) from the same institution. He is also a distinguished graduate of the USAF ROTC program.
