Multiple-input multiple-output over-the-horizon radar: experimental results
IET Radar, Sonar and Navigation, 2009 Results from an experiment that applied one class of multiple-input multiple-output (MIMO) waveform techniques to over-the-horizon radar (OTHR) are reported. The experiment objective was to demonstrate that adaptive transmitter beamforming could be used in an appropriately design radar to reject spatially discrete Doppler-spread clutter.

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.

Multiple-input multiple-output radar detectors design in non-Gaussian clutter
IET Radar, Sonar and Navigation, 2010 This study mainly deals with the problem of multiple-input multiple-output (MIMO) radar in compound-Gaussian clutter-dominated scenario with unknown covariance matrix. The general MIMO model, with widely separated sub-arrays and co-located antennas at each sub-array, is adopted.

Ultra wideband multiple-input multiple-output radar [PDF]
IEEE International Radar Conference, 2005., 2005 The utilization of ultra wideband (UWB) signals enables the radar designer to solve the most important problems of radar target observation. The extremely wide bandwidth enables greater information to be obtained due to high time resolution and the frequency dependence of the scattering centers over this large bandwidth.
