EC-GLRT: Detecting Weak Plumes in Non-Gaussian Hyperspectral Clutter Using an Elliptically-Contoured Generalized Likelihood Ratio Test [PDF]

open access: yesIGARSS 2008 - 2008 IEEE International Geoscience and Remote Sensing Symposium, 2008
We investigate the behavior of a detector for weak gaseous plumes in hyperspectral imagery that can be derived in terms of a generalized likelihood ratio test (GLRT) applied to an elliptically-contoured (EC) model for the distribution of background clutter.

GDTF: Generalized Detection Theoretic Framework for T-Wave Alternans Analysis

open access: yesIEEE Access, 2020
Detection and estimation of t-wave alternans (TWA) in presence of indispensable physiological artifacts is still a challenging task, as in most of the cases, the signal of interest resides well below the noise levels.

Aspect-Aware Target Detection and Localization by Wireless Sensor Networks

open access: yesSensors, 2018
This paper considers the active detection of a stealth target with aspect dependent reflection (e.g., submarine, aircraft, etc.) using wireless sensor networks (WSNs). When the target is detected, its localization is also of interest.

Statistical test for GNSS spoofing attack detection by using multiple receivers on a rigid body

open access: yesEURASIP Journal on Advances in Signal Processing, 2020
Global navigation satellite systems (GNSS) are being the target of various jamming, spoofing, and meaconing attacks. This paper proposes a new statistical test for the presence of multiple spoofers based on range measurements observed by a plurality of ...

Compressive Detection Using Sub-Nyquist Radars for Sparse Signals

open access: yesInternational Journal of Antennas and Propagation, 2016
This paper investigates the compression detection problem using sub-Nyquist radars, which is well suited to the scenario of high bandwidths in real-time processing because it would significantly reduce the computational burden and save power consumption ...

Spectrum Sensor Employing Continuous Pilot Tones in Cognitive Radio Systems

open access: yesIEEE Access, 2017
Despite the promising role of orthogonal frequency-division multiplexing (OFDM) in communication systems, the optimal and practical spectrum sensing of OFDM signals for cognitive radio systems over multipath fading channels remains an important and ...
