Dr. Zhang serves as a guest editor for a Digital Signal Processing<\/em> special issue on “Co-prime Sampling and Arrays”<\/a>. The special issue is currently accepting paper submissions until January 15, 2016. \u00a0The co-guest editors are Dr.\u00a0Moeness G. Amin from the Center for Advanced Communications, Villanova University, Dr. P.P. Vaidyanathan from Department of Electrical Engineering, California Institute of Technology, and Dr.\u00a0Piya Pal from Department of Electrical and Computer Engineering, University of Maryland.<\/p>\n Co-prime sampling and co-prime arrays have recently been shown to improve active and passive sensing in radar and underwater acoustics using both narrowband and wideband signal platforms. Co-prime processing provides a systematical framework for sparse sampling and array configuration with increased aperture and improved spatial resolution. Co-prime based approaches to sampling and arrays can combat ambiguity and provide unique answers to target coordinates under forced coarse sampling in time, frequency, and space. Temporal and spatial co-prime samplings make advances in direction-of-arrival (DOA) estimation, spectrum sensing, and sparse covariance sketching. They find broad applications in synthetic aperture radar (SAR), radio frequency (RF) surveillance, target localization, wideband urban radar processing, space\u2013time adaptive processing, and nonstationary array processing utilizing Doppler signatures and instantaneous frequency source characteristics.<\/p>\n The goal of the Special Issue is to publish the most recent results in signal processing using co-prime sampling and arrays. Review papers on this topic are also welcome.
