Phased-MIMO Radar: A Tradeoff Between Phased-Array and MIMO Radars [PDF]
IEEE Transactions on Signal Processing, 2010 We propose a new technique for multiple-input multiple-output (MIMO) radar with colocated antennas which we call phased-MIMO radar. The new technique enjoys the advantages of MIMO radar without sacrificing the main advantage of phased-array radar which is the coherent processing gain at the transmitting side. The essence of the proposed technique is to

LiQuiD-MIMO Radar: Distributed MIMO Radar with Low-Bit Quantization
ICASSP 2023 - 2023 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2023 Distributed MIMO radar is known to achieve superior sensing performance by employing widely separated antennas. However, it is challenging to implement a low-complexity distributed MIMO radar due to the complex operations at both the receivers and the fusion center.

MIMO-MC radar: A MIMO radar approach based on matrix completion [PDF]
IEEE Transactions on Aerospace and Electronic Systems, 2015 In a typical MIMO radar scenario, transmit nodes transmit orthogonal waveforms, while each receive node performs matched filtering with the known set of transmit waveforms, and forwards the results to the fusion center. Based on the data it receives from multiple antennas, the fusion center formulates a matrix, which, in conjunction with standard array

Compressive sensing for MIMO radar [PDF]
2009 IEEE International Conference on Acoustics, Speech and Signal Processing, 2009 Multiple-input multiple-output (MIMO) radar systems have been shown to achieve superior resolution as compared to traditional radar systems with the same number of transmit and receive antennas. This paper considers a distributed MIMO radar scenario, in which each transmit element is a node in a wireless network, and investigates the use of compressive

Coded OFDM Waveforms for MIMO Radars [PDF]
IEEE Transactions on Vehicular Technology, 2021 Emerging digital radar concepts such as orthogonal frequency-division multiplexing (OFDM) allow flexible signal generation. This opens up new opportunities in waveform design in a multiple-input multiple-output (MIMO) system such as introducing coding for signal multiplexing. In this article, coded MIMO OFDM waveforms are proposed and investigated that

Compressed sensing in MIMO radar [PDF]
2008 42nd Asilomar Conference on Signals, Systems and Computers, 2008 Compressed sensing is a technique for efficiently sampling signals which are sparse in some transform domain. Recently, the idea of compressed sensing has been used in the radar system. When the number of targets on the range-Doppler plane is small, the target scene can be reconstructed by employing the compressed sensing techniques.

Super-resolution MIMO radar [PDF]
2016 IEEE International Symposium on Information Theory (ISIT), 2016 A multiple input, multiple output (MIMO) radar emits probings signals with multiple transmit antennas and records the reflections from targets with multiple receive antennas. Estimating the relative angles, delays, and Doppler shifts from the received signals allows to determine the locations and velocities of the targets.
