IEEE Communications Letters, 2022 Nowadays, sparse multiple input and multiple output (MIMO) radar design considers the difference coarray of the sum coarray (DCSC) concept and the uniform degrees of freedom is improved significantly. Current sparse MIMO arrays are designed based on transmit and receive arrays with hole-free difference coarrays (DCAs).

Adaptive waveform design for imaging MIMO radar systems
, 2022 6 S.One limitation of MIMO imaging radar systems is the waveform diversity available for the transmitters. Indeed, different properties for the transmitted signals, such as orthogonality and Doppler tolerance, are required in order to obtain good imaging

MIMO noise radar - matched filters and coarrays [PDF]
, 2008 Copyright © 2008 IEEEThe noise radar concept can be extended to an array of K transmit antenna and M receive antenna. When independent noise sources are transmitted from each antenna the approach may be viewed as a special case of MIMO radar and matched ...

Minimum redundancy MIMO radars [PDF]
2008 IEEE International Symposium on Circuits and Systems (ISCAS), 2008 The multiple-input multiple-output (MIMO) radar concept has drawn considerable attention recently. In the traditional single-input multiple-output (SIMO) radar system, the transmitter emits scaled versions of a single waveform. However, in the MIMO radar system, the transmitter transmits independent waveforms.

Detection Performance of Noncoherent Radar: MIMO Radar, Phased Array Radar, Directional MIMO Radar
The Journal of Korean Institute of Communications and Information Sciences, 2011 In a traditional phased array radar, closely spaced antenna elements transmit a scaled version of single waveform to maximize the signal energy. On the contrary, a multiple-input multiple-output (MIMO) radar consists of widely separated antennas and transmits an arbitrary waveform from each antenna element.

, 2023 We show the concept of multiple-input multiple-output (MIMO) radar and introduce practical applications, which include ground based synthetic aperture radar (GB-SAR) and ground penetrating radar (GPR). As an example, a 17 GHz MIMO GB-SAR system to be used for landslide monitoring and infrastructure measurement is described. We also show that a MIMO GPR

Applied and Computational Harmonic Analysis, 2014 We consider a multiple-input-multiple-output radar system and derive a theoretical framework for the recoverability of targets in the azimuth-range domain and the azimuth-range-Doppler domain via sparse approximation algorithms. Using tools developed in the area of compressive sensing, we prove bounds on the number of detectable targets and the ...
