Multifunctionality In Radar: A Massive MIMO Radar Paradigm
2020 54th Asilomar Conference on Signals, Systems, and Computers, 2020Our research considers a radar which employs an aperture consisting of thousands of elements with multifunctional MIMO capabilities. The increased spatial degrees of freedom permits the radar to be multi-functional without significantly sacrificing desired beamwidth and angular resolution.

Plane localisation for MIMO radar
2014 International Radar Conference, 2014We address the problem of estimating the surface profile of the ground from an airborne platform with a forward looking MIMO radar. In particular we are interested in developing a landing aid for helicopters in degraded visibility. In this paper we present an algorithm for fitting a plane surface to the data obtained from a coherent co-located MIMO ...

On Parameter Identifiability of MIMO Radar
IEEE Signal Processing Letters, 2007A multi-input multi-output (MIMO) radar system, unlike a standard phased-array radar, can transmit multiple linearly independent probing signals via its antennas. We show herein that this waveform diversity enables the MIMO radar to significantly improve its parameter identifiability. Specifically, we show that the maximum number of targets that can be

The MIMO Radar and Jammer Games
IEEE Transactions on Signal Processing, 2012The interaction between a smart target and a smart MIMO radar is investigated from a game theory perspective. Since the target and the radar form an adversarial system, their interaction is modeled as a two-person zero-sum game. The mutual information criterion is used in formulating the utility functions.

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.
