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 ...

Constant false alarm rate detection method in polarimetric synthetic aperture radar imagery based on whitening filter under inverse beta distribution

open access: yesThe Journal of Engineering, 2019
The constant false alarm rate (CFAR) detection method based on multi-look polarisation whitening filter (MPWF) has not been obtained in the polarimetric synthetic aperture radar imagery when the texture variable obeys the Inverse Beta distribution.

Metal Organic Framework‐Modified Carbon Fiber Microelectrodes for Enhanced Neurochemical Detection

open access: yesChemElectroChem, Volume 13, Issue 8, 15 April 2026.
In this work, we modified carbon fiber microelectrodes (CFMEs) with the iron‐based metal organic framework MIL‐88B(Fe) and examined their performance using fast scan cyclic voltammetry (FSCV). The modification enhanced the dopamine signal at low concentrations and enabled consistent nanomolar detection, while maintaining clear peak separation in ...

Optimum CFAR detection against compound gaussian clutter with partially correlated texture

open access: yes, 1996
The paper deals with CFAR detection in compound Gaussian clutter with a partially correlated texture component. A theoretical high performance upgrade has been demonstrated using the ideal exact knowledge of this component in the CFAR scheme ('ideal CFAR'

SPH Simulates Steep‐Stepped Spillway Flows Assessing Convergence, DDT Effects, and Pressure Accuracy

open access: yesChemical Engineering &Technology, Volume 49, Issue 4, April 2026.
Numerical investigation of high‐gradient stepped spillway flows using the SPH method, highlighting the simulation setup and skimming flow regime. Convergence analysis compares results with and without the Density Diffusion Term (DDT), showing its effectiveness in reducing spurious oscillations.

Non Coherent Radar CFAR Detection Based On Goodness-Of-Fit Tests

open access: yes, 2007
This paper considers the problem of constant false alarm rate (CFAR) detection of radar targets using multiple observations. In the Gaussian clutter scenario, the structure of the optimum (uniformly most powerful) CFAR detector is rather simple, but when

REVIEW OF RADAR DETECTORS WITH CONSTANT FALSE ALARM RATE

open access: yesTelemática, 2020
Radar detection in environments with high spatial and temporal variability is an issue of great importance. Many efforts are devoted to the development of adaptive techniques that allow robust operation for all possible scenarios.

Altered Cytokine‐Induced STAT3 and STAT5 Activation of Peripheral T Follicular Helper Cells Contributes to Vaccine‐Non‐Responsiveness in Aging and HIV

open access: yesAging Cell, Volume 25, Issue 3, March 2026.
Chronic immune activation and inflammation associated with aging and HIV skew Tfh signaling toward enhanced IL‐2–STAT5 activation, reinforcing IL‐2R expression through a positive feedback loop and suppressing Tfh helper differentiation programs, thereby contributing to impaired vaccine responsiveness.

Parallel Distributed CFAR Detection Optimization Based on Genetic Algorithm with Interval Encoding

open access: yes, 2010
Aiming at parallel distributed constant false alarm rate (CFAR) detection employing K/N fusion rule, an optimization algorithm based on the genetic algorithm with interval encoding is proposed.
