CFAR Target Detector in Synthetic Aperture Radar
Известия высших учебных заведений России: РадиоэлектроникаIntroduction. 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 ...

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