Matched direction detectors [PDF]
, 2005 In this paper, we address the problem of detecting a signal whose associated spatial signature is subject to uncertainties, in the presence of subspace interference and broadband noise, and using multiple snapshots from an array of sensors.

Detection in the presence of surprise or undernulled interference [PDF]
, 2007 We consider the problem of detecting a signal of interest in the presence of colored noise, in the case of a covariance mismatch between the test cell and the training samples. More precisely, we consider a situation where an interfering signal (e.g., a

An ABORT-like detector with improved mismatched signals rejection capabilities [PDF]
, 2008 In this paper, we present a GLRT-based adaptive detection algorithm for extended targets with improved rejection capabilities of mismatched signals. We assume that a set of secondary data is available and that noise returns in primary and secondary data ...

Adaptive detection with bounded steering vectors mismatch angle [PDF]
, 2007 We address the problem of detecting a signal of interest (SOI), using multiple observations in the primary data, in a background of noise with unknown covariance matrix.

Aspect-Aware Target Detection and Localization by Wireless Sensor Networks
Sensors, 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
EURASIP 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 ...

Coherent network analysis for continuous gravitational wave signals in a pulsar timing array: Pulsar phases as extrinsic parameters [PDF]
, 2015 Supermassive black hole binaries are one of the primary targets for gravitational wave searches using pulsar timing arrays. Gravitational wave signals from such systems are well represented by parametrized models, allowing the standard Generalized ...

Compressive Detection Using Sub-Nyquist Radars for Sparse Signals
International 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 ...
