CFAR Target Detector in Synthetic Aperture Radar

Известия высших учебных заведений России: Радиоэлектроника
Introduction. Constant false alarm rate (CFAR) detectors have found application in synthetic aperture radar (SAR) systems. The operating principle of a classic cell averaging detector (CA-CFAR detector) is based on comparing the decision statistics in ...

CFAR based NOMP for Line Spectral Estimation and Detection

, 2022
The line spectrum estimation problem is considered in this paper. We propose a CFAR-based Newtonized OMP (NOMP-CFAR) method which can maintain a desired false alarm rate without the knowledge of the noise variance.

Closed-Form Solution for CFAR Detection Threshold in G⁰ Distributed SAR Clutter

IEEE Access
We devise a constant false alarm rate (CFAR) detector for detecting targets in clutter regions with varying degrees of heterogeneity. The CFAR detector employs the $\mathcal {G}^{0}$ distribution for characterizing the statistics of background ...
