Time Reversal in Multiple-Input Multiple-Output Radar [PDF]

IEEE Journal on Selected Topics in Signal Processing, 2010
Time reversal explores the rich scattering in a multipath environment to achieve high target detectability. Multiple-input multiple-output (MIMO) radar is an emerging active sensing technology that uses diverse waveforms transmitted from widely spaced antennas to achieve increased target sensitivity when compared to standard phased arrays.

Multiple-input multiple-output radar aperture optimisation

IET Radar, Sonar and Navigation, 2011
The authors describe a process for designing low-cost, light-weight antenna apertures for use in multiple-input multiple-output (MIMO) radars. In a MIMO radar system, two or more transmitters emit independent waveforms, with the resulting reflections received by an array of receivers. Recently, MIMO radar has become a subject of great interest. In part,

Parameter estimation and identifiability in bistatic multiple-input multiple-output radar

IEEE Transactions on Aerospace and Electronic Systems, 2015
An iterative ESPRIT-like algorithm is devised for direction-of-departure (DOD) and direction-of-arrival (DOA) estimation in multiple-input multiple-output radar. Our proposal can handle identical DODs and DOAs, and provides autopairing of the angle parameters. Furthermore, it is proved that the multiple signal classification methodology cannot identify

Multiple Input-Multiple Output Quantum Radar

2020 IEEE Radar Conference (RadarConf20), 2020
We consider a quantum radar, using as sources for entangled photons devices with spontaneous parametric downconversion, with a given number of channels. This conception is similar to a MIMO radar and we exploit the detection theory for this case to show a neat improvement in the receiver operating characteristics (ROC) curves with increasing number of ...

Target localisation techniques and tools for multiple-input multiple-output radar

IET Radar, Sonar and Navigation, 2009
This study presents a comparative study of coherent and non-coherent target localisation techniques for multiple-input multiple-output (MIMO) radar systems with widely distributed elements. Performance is evaluated based on closed-form solutions developed for the best linear unbiased estimator (BLUE) for each of the localisation methods.

Target Localization and Tracking in Noncoherent Multiple-Input Multiple-Output Radar Systems

IEEE Transactions on Aerospace and Electronic Systems, 2012
For a noncoherent multiple-input multiple-output (MIMO) radar system, the maximum likelihood estimator (MLE) of the target location and velocity, as well as the corresponding Cramer-Rao lower bound (CRLB) matrix, is derived. MIMO radar's potential in localization and tracking performance is demonstrated by adopting simple Gaussian pulse waveforms.
