Robust CFAR Detector Based on Truncated Statistics for Polarimetric Synthetic Aperture Radar [PDF]
, 2020 Constant false alarm rate (CFAR) algorithms using a local training window are widely used for ship detection with synthetic aperture radar (SAR) imagery. However, when the density of the targets is high, such as in busy shipping lines and crowded harbors,

A comparison of constant false alarm rate object detection algorithms for iceberg identification in L- and C-band SAR imagery of the Labrador Sea [PDF]
The Cryosphere, 2023 In this study, we pursue two objectives: first, we compare six different “constant false alarm rate” (CFAR) algorithms for iceberg detection in SAR images, and second, we investigate the effect of radar frequency by comparing the detection performance at

MIMO radar techniques: two-stage constant false alarm rate detection for fast-fluctuating targets
The Journal of Engineering, 2019 Here, the authors analyse a two-step constant false alarm rate (CFAR) detection problem in distributed sensor system (e.g. statistical multiple-input multiple-output (MIMO) radar) for fast-fluctuating targets (TS-AMF-II).

An improved adaptive sidelobe blanker [PDF]
, 2008 We propose a two-stage detector consisting of a subspace detector followed by the whitened adaptive beamformer orthogonal rejection test. The performance analysis shows that it possesses the constant false alarm rate property with respect to the unknown

Analysis of cooperative jamming against pulse compression radar based on CFAR
EURASIP Journal on Advances in Signal Processing, 2018 One important issue in radar jamming is the effect of inaccuracies in the radar position, which leads to a number of false targets entering the reference window of the constant false alarm ratio (CFAR) detector to reduce greatly.

Detection of Ground Moving Targets for Two-Channel Spaceborne SAR-ATI
EURASIP Journal on Advances in Signal Processing, 2010 Many present spaceborne synthetic aperture radar (SAR) systems are constrained to only two channels for ground moving target indication (GMTI). Along-track interferometry (ATI) technique is currently exploited to detect slowly moving targets and measure
