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.

Correlation characteristic analysis in diversity multiple‐input multiple‐output radar
Electronics Letters, 2017 A huge limitation of the correlation analysis in existing scatterer model is that only uniformly distributed scatterers are considered ignoring the variability of scattering intensity in the real situation.

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,
