The dependence of radar target detectability on array weighting function [PDF]
, 2009 Presented at the IET-Radar 2007 Conference Edinburgh 15-18 October 2007This paper describes simulation work to assess the detectability of targets by an airborne fire control radar (FCR) operating in a medium pulse repetition frequency (PRF) mode in ...

Developments in target micro-Doppler signatures analysis : radar imaging, ultrasound and through-the-wall radar [PDF]
, 2013 Target motions, other than the main bulk translation of the target, induce Doppler modulations around the main Doppler shift that form what is commonly called a target micro-Doppler signature.

Frontiers in Computer Science, 2022 IntroductionThis paper proposes a Bayesian surprise learning algorithm that internally motivates the cognitive radar to estimate a target's state (i.e., velocity, distance) from noisy measurements and make decisions to reduce the estimation error ...

Designing Sequences With Minimized Mean Sidelobe Level for Cognitive Radars
IEEE Access, 2021 In this paper, a set of sequences is developed with a minimized mean sidelobe level (MSL). The problem is formulated for cognitive radars using the $l_{1}$ -norm, where the target cognition determines which sidelobes should be suppressed.

Moving target detection and tracking with multiplatform radar network (MRN)
IET Radar, Sonar & Navigation, 2022 A multiplatform radar network (MRN) composed of multiple transmitting and receiving facilities is advantageous over monostatic radar in moving target detection (MTD) and tracking due to the diversity gain.

Temporal-Targeted Accelerated 40 Hz tACS Enhances Cognitive Function and Network Integration in Alzheimer's Disease: A Randomized Clinical Trial. [PDF]
Adv Sci (Weinh)Bilateral temporal accelerated 40‐Hz tACS improves cognitive function in patients with Alzheimer's disease. Resting‐state fNIRS identifies treatment‐related increases in frontotemporoparietal functional connectivity, which are associated with cognitive improvement. ABSTRACT The temporal lobes are key hubs for memory and cognition.

A 2D processing algorithm for detecting landmines using Ground Penetrating Radar data [PDF]
, 2012 Ground Penetrating Radar(GPR) is one of a number of technologies that have been used to improve landmine detection efficiency. The clutter environment within the first few cm of the soil where landmines are buried, exhibits strong reflections with ...
