Radar data extraction and constant false alarm rate (CFAR) processing

open access: yes, 2002
Digital signal processing is essential to any modern radar and communication system. The motivation of this research was aimed to develope the analog-to-digital converter and Constant False Alarm Rate (CFAR) detector of the radar signal processing system.

Towards an Integrative Perspective of the Actively Involved Person in Mental Health Care: A Concept Mapping Approach

open access: yesJournal of Clinical Psychology, EarlyView.
ABSTRACT Objective The importance of being actively involved in dealing with mental health care problems is well‐recognized. Many terms and ideas have been introduced to explicate this active involvement, but to date, there is no consensus about a definition.

Temporal dynamics of visual awareness and target detection revealed by EEG‐based univariate and multivariate analyses

open access: yesJournal of Intelligent Medicine, EarlyView.
In this study, we combined univariate ERP analysis with multivariate decoding of EEG data to examine target detection and reported visual awareness in a near‐threshold visual task. The results revealed partly overlapping yet distinguishable temporal dynamics associated with the two processes.

Wilcoxon Nonparametric CFAR Scheme for Ship Detection in SAR Image

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
The parametric constant false alarm rate (CFAR) detection algorithms, which are based on various statistical distributions, such as Gaussian, Gamma, Weibull, log-normal, $G^{0}$, and alpha-stable distribution, are most widely used to detect the ship ...

Harmful intrusion detection algorithm of optical fiber pre-warning system based on correlation of orthogonal polarization signals

open access: yesPhotonic Sensors, 2017
At present, advanced researches of optical fiber intrusion measurement are based on the constant false alarm rate (CFAR) algorithm. Although these conventional methods overcome the interference of non-stationary random signals, there are still a large ...

Lightning electromagnetic emission location using arrival time differencing (LEELA): An introduction to the Met Office's next generation Very Low Frequency lightning location system

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
This paper describes the Met Office's new lightning location system LEELA. A brief overview of the upgraded hardware and geolocation algorithms is given. LEELA has improved lightning detection capabilities, especially at night. When comparing LEELA to the previous ATDnet system against ground truths LEELA has 100% storm detection efficiency within 5 km

Enhancing severe convection forecasts with microwave radiance assimilation in limited‐area models

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
Microwave satellite radiances remain largely underexploited in convection‐permitting limited‐area models. We assess the assimilation of humidity‐sensitive radiances from the MHS instrument in the operational ICON‐2I model, improving the precipitation forecast of a severe convective event over the Marche region, Italy, substantially by correcting ...

The Software-Based Implementation of the CFAR Reciever for the Processing of the Radar Signal

open access: yesAdvances in Electrical and Electronic Engineering, 2007
The performance of a radar receiver is greatly dependent on the presence of noise. The receiver should achieve the constant false alarm rate (CFAR) and the maximum probability of the target detection.
