Adaptive Constant False Alarm Detector Based on Composite Fuzzy Fusion Rules
In order to improve the detection performance of the radar constant false alarm detector in a multiple-target environment, a Kaigh–Lachenbruch Quantile constant false alarm rate detector based on composite fuzzy fusion rules (CFKLQ-CFAR) is designed by ...

False Alarm Analysis of the CATM-CFAR in Presence of Clutter Edge
This paper presents a false alarm analysis of the cell-averaging-trimmed-mean constant false alarm rate (CATM-CFAR) detector in the presence of clutter edge. Structure of the CATM-CFAR detector is described briefly.

Wilcoxon Nonparametric CFAR Scheme for Ship Detection in SAR Image [PDF]
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 (CFAR) detection based estimators with applications to sparse wireless channels [PDF]
We provide Constant False Alarm Rate (CFAR) based thresholding methods for training based channel impulse response (CIR) estimation algorithms for communication systems which utilize a periodically transmitted training sequence within a continuous stream of information symbols. After obtaining the CIR estimation by using known methods in the literature,

An Adaptive Autogram Approach Based on a CFAR Detector for Incipient Cavitation Detection
Cavitation failure often occurs in centrifugal pumps, resulting in severe harm to their performance and life-span. Nowadays, it has become crucial to detect incipient cavitation ahead of cavitation failure.

Statistical Properties of Energy Detection for Spectrum Sensing by Using Estimated Noise Variance
In energy detection for cognitive radio spectrum sensing, the noise variance is usually assumed given, by which a threshold is set to guarantee a desired constant false alarm rate (CFAR) or a constant detection rate (CDR).
