A Novel Method for Estimating Heart Rate Variability Through a Multiple-Input Multiple-Output FMCW Radar

IEEE Access
In this manuscript, the problem of assessing the heart rate variability (HRV) of a single subject using a colocated multiple-input multiple-output radar of frequency modulated continuous wave type is investigated.

Othogonal Waveform Design for Multiple-Input Multiple-Output (MIMO) Radar

Open Journal of Applied Sciences, 2012
An effective numerical approach is developed for orthogonal waveform design for Multiple-Input Multiple-Output (MIMO) radar. The Doppler shift tolerance is considered in the design cost function. The design results indicate that the Doppler  tolerance of the designed orthogonal waveforms is markedly improved.

Field Trial of Cluster Target Detection by Broadband Microwave Photonic MIMO Radar

IEEE Journal of Microwaves
Cluster target detection is challenging for traditional narrow-band radars. Microwave photonic multiple-input-multiple-output (MIMO) radar is an emerging technique for accurate cluster target detection, which enhances range and angular resolution via its

Thinned MIMO arrays with constrained element spacing for imaging radar

, 2012
Thinned multiple-input multiple-output (MIMO) antenna arrays with constrained element spacing are considered for imaging radar. It is shown that, in contrast to classical MIMO arrays, the minimum element spacing can be chosen to be a multiple of half the
