CFAR Detectors for MIMO Radars
Circuits, Systems, and Signal Processing, 2012CFAR (Constant False-Alarm Rate) processors are useful for detecting radar targets in a background for which the parameters in the statistical distribution are not known. A variety of CFAR techniques such as CA (Cell Averaging), Go (Greatest Of), SO (Smallest Of), OS (Ordered Statistics) and ACMLD (Automatic Censored Mean-Level Detector) processors ...

MIMO radar target measurements
2011 Conference Record of the Forty Fifth Asilomar Conference on Signals, Systems and Computers (ASILOMAR), 2011Widely-spaced Multiple-Input Multiple-Output (MIMO) radar seeks to exploit an angular diversity of measurements in order to improve target detection performance. Such systems have been predicted to outperform equivalent phased-array configurations given a suitably low-noise environment.

2010 IEEE International Geoscience and Remote Sensing Symposium, 2010
In addition to imaging, coherent MIMO radars have a strong potential for detecting moving objects and estimating their parameters. This paper investigates different MIMO schemes based on spatial, waveform, and frequency diversity for their GMTI capability.

MIMO Radar Ambiguity Functions
IEEE Journal of Selected Topics in Signal Processing, 2006Multiple-input multiple-output (MIMO) radar has been shown to provide enhanced performance in theory and in practice. MIMO radars are equipped with the ability to freely choose their transmitted waveforms at each aperture. In conventional radar systems Woodward's ambiguity function is used to characterize waveform resolution performance.

Robust Waveform Design for MIMO Radars
IEEE Transactions on Signal Processing, 2011The problem of robust waveform design for multiple-input, multiple-output radars equipped with widely spaced antennas is addressed here. Robust design is needed as a number of parameters may be unknown, e.g., the target scattering covariance matrix and the disturbance covariance matrix.

CSSF MIMO RADAR: Compressive-Sensing and Step-Frequency Based MIMO Radar
IEEE Transactions on Aerospace and Electronic Systems, 2012A new approach is proposed, namely CSSF MIMO radar, which applies the technique of step frequency (SF) to compressive sensing (CS) based multiple-input multiple-output (MIMO) radar. The proposed approach enables high resolution range, angle and Doppler estimation, while transmitting narrowband pulses.

2018 International Carnahan Conference on Security Technology (ICCST), 2018
Multiple Input Multiple Output (MIMO) cable guided radar presents a true paradigm shift in leaky coaxial cable sensing. Recent technology advancements in Software Defined Radio (SDR) allow this covert terrain following radar to provide reliable detection and pinpoint the location of intruders as they cross the perimeter.

On Transmit Beamforming for MIMO Radar
IEEE Transactions on Aerospace and Electronic Systems, 2012Methods for transmit beamforming in multiple-input multiple-output (MIMO) radar based on the design of multiple correlated waveforms have been proposed. This paper points out that this approach couples the spatial (beamformer) and temporal (waveform) parts of the problem, significantly complicating the design.

On spatial processing in MIMO radar
2011 Conference Record of the Forty Fifth Asilomar Conference on Signals, Systems and Computers (ASILOMAR), 2011We develop a signal model for MIMO radar which takes into account delay and Doppler mismatch due to the fact that scatterers do not generally lie in the center of delay/Doppler resolution cells, as is commonly assumed in the literature on this subject.
