Title: Commercial MIMO Radar Successes and Challenges

Abstract: Unlike a standard phased-array radar, MIMO radar can transmit via its antennas multiple probing signals that may be correlated or uncorrelated with each other. We provide herein an overview of some recent results on MIMO radar with colocated antennas, showing that this waveform diversity enables the MIMO radar superiority in several fundamental aspects. Moreover, we discuss several commercial MIMO radar developments, including the highly successful automotive MIMO radar developments. Driven by autonomous driving demands, the automotive radar industry is already a multi-billion-dollar industry! Furthermore, to deal with mutual interference mitigation challenges encountered in commercial MIMO radar systems, probing waveform synthesis for MIMO radar is also discussed. We will provide a review of novel, cyclic approaches to single and multiple probing waveform designs. Both aperiodic and periodic correlations will be considered. We show that by making use of fast Fourier transforms (FFTs), we can now efficiently design sequences that were previously impossible to synthesize. We will also briefly present recent developments on slow-time code designs to achieve low-cost mutual interference mitigations.
