MIMO RADAR WITH COLOCATED ANTENNAS


A MIMO (multi-input multi-output) radar system, unlike a standard phased-array radar, can transmit via its antennas multiple probing signals that may be correlated or uncorrelated with each other. We provide herein an overview of our recent results on MIMO radar with colocated antennas, showing that this waveform diversity enables the MIMO radar superiority in several fundamental aspects, including significantly improved parameter identifiability and much enhanced flexibility for transmit beampattern design. Moreover, we discuss the challenges and advances of using MIMO radar and space-time adaptive processing for enhanced ground moving target indication. Finally, we comment in passing on diverse expert opinions on MIMO radar.
