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 ...

Modified Generalized Likelihood Ratio Test Detection Based on a Symmetrically Spaced Linear Array in Partially Homogeneous Environments

open access: yesLeida xuebao, 2021
To address the problem of detecting point-like targets in a partially homogeneous Gaussian cluttered environment, we developed a modified Generalized Likelihood Ratio Test (GLRT) detection method based on a symmetrically spaced linear array that relies ...

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 ...

An Adaptive OFDM Detection Strategy for Range and Doppler Spread Targets in Non-Gaussian Clutter

open access: yesIEEE Access, 2018
Orthogonal frequency division multiplexing (OFDM) radar can obtain higher target detection performance than traditional single carrier frequency radar due to simultaneously multiple frequency measurements.

Moving Target Detection Using Distributed MIMO Radar Based on Low-bit Quantization under the Background of Generalized Gaussian Noise

open access: yesLeida xuebao
Signal-level cooperative detection based on multichannel observations is a pivotal technique in distributed Multiple-Input Multiple-Output (MIMO) radar for probing targets via the joint processing of multiple echo channels.

A Fast Blind Detection Algorithm for Outdoor Visible Light Communications

open access: yesIEEE Photonics Journal, 2015
In this paper, we consider an outdoor visible light communication system, in which on-off keying (OOK) modulation is utilized through an atmospheric turbulence-induced slow-fading channel. A new fast blind detection algorithm is proposed by following the

Adaptive detection of a signal known only to lie on a line in a known subspace, when primary and secondary data are partially homogeneous [PDF]

open access: yes, 2006
This paper deals with the problem of detecting a signal, known only to lie on a line in a subspace, in the presence of unknown noise, using multiple snapshots in the primary data.
