High-Resolution Sparse Subband Imaging Based on Bayesian Learning With Hierarchical Priors
Feng Zhou,Xueru Bai +1 more
TL;DR: A novel method for high-resolution sparse subband imaging based on Bayesian learning using hierarchical sparse-promoting priors on the distribution of scattering centers and a closed-form solution based on the MAP-expectation–maximization framework is proposed.
Journal ArticleDOI
High-Resolution Three-Dimensional Imaging of Space Targets in Micromotion
Xueru Bai,Feng Zhou,Zheng Bao +2 more
TL;DR: A nonparametric 3-D imaging method based on scattering center trajectory association is proposed that deals with target occlusion using the Riemannian manifold optimization and obtains focused imaging of targets in complex micromotion.
Journal ArticleDOI
High-Resolution Radar Imaging in Complex Environments Based on Bayesian Learning With Mixture Models
Xueru Bai,Zhang Yu,Feng Zhou +2 more
TL;DR: Experiments have shown that accounting for the noise with Gaussian mixture model instead of single Gaussian greatly improves the performance, and the proposed method provides an effective way of high-resolution radar imaging in complex environments such as barrage jamming and micro-Doppler interference.
Dissertation
A coherent microwave interface for manipulation of single optical photons
TL;DR: In this article, a photonic qubit is used to store information encoded in photons into Rydberg excitations in a cloud of cold atoms, where strong dipole-dipole interactions induce interactions between qubits.
Journal ArticleDOI
Radar Image Series Denoising of Space Targets Based on Gaussian Process Regression
Xueru Bai,Xin Peng +1 more
TL;DR: This work addresses the problem of image series denoising for high-resolution radar in a nonparametric Bayesian framework by exploiting the characteristics of amplitude variation at different pixels in the image series and imposes the Gaussian process (GP) model to the corresponding time series of each pixel.

Wideband Radar for Ballistic Missile Defense and Range- Doppler Imaging of Satellites
William W. Camp,Joseph T. Mayhan +1 more
TL;DR: The first wideband radar, called ALCOR, was deployed at Kwajalein Atoll in 1970 by the National Institute of Aeronautics and Astronautics (NICA) as discussed by the authors.
Journal ArticleDOI
The 100-kW millimeter-wave radar at the Kwajalein Atoll
M.D. Abouzahra,R.K. Avent +1 more
TL;DR: The authors begin by giving a superficial discussion of the Kiernan Reentry Measurements Site (KREMS) program, of which MMW is an active participant, and the suite of sensors located there and the system description includes a discussion concerning the transmitter, antenna, receiver, and signal-processing systems.
Proceedings ArticleDOI
Radar open systems architecture and applications
TL;DR: This paper presents the radar open systems architecture (ROSA) that has been used successfully in building the prototype Cobra Gemini radar and is currently being used to modernize four unique signature radars at the Kwajalein Missile Range (KMR) and three unique radARS at the Millstone Hill radar facility.
Journal ArticleDOI
Net centric radar technology & development using an open system architecture approach
TL;DR: The second generation of the Radar Open Systems Architecture has been developed and put into practice, which consists of a layered architecture that isolates applications from underlying hardware and software elements such as operating systems, middlewares, communication fabrics, and computer platforms.
Proceedings ArticleDOI
The role of quasi-optics at the 35 GHz millimeter-wave radar
TL;DR: In this article, the authors describe the current 35 GHz system configuratior with emphasis on the quasi-optical dual-tube power amplifier combiner and the beam waveguide antenna feed system.
