Non-trained Oil Slicks CFAR Detection based upon (possibly Polarimetric) SAR Data
, 2004 This paper addresses CFAR detection of oil slicks on the ocean surface by resorting to possibly polarimetric SAR data. The proposed GLRT-based detectors do not require secondary data (namely pixels from a slick-free area); remarkably, the performance

CATM-CFAR detector in the receiver of the software defined radar [PDF]
Scientific Technical Review, 2014 This paper presents a model of the CATM-CFAR detector in the receiver of the software defined radar. The mentioned detector is named cell-averaging-trimmed-mean CFAR. It is a combination of cell-averaging and trimmed mean CFAR.

A Correlation-Based Joint CFAR Detector Using Adaptively-Truncated Statistics in SAR Imagery
, 2017 Traditional constant false alarm rate (CFAR) detectors only use the contrast information between ship targets and clutter, and they suffer probability of detection (PD) degradation in multiple target situations.

Hypothesis testing and decision making: Constant-false-alarm-rate detection
, 2009 Detection is the first task in establishing a communication link, or tracking a target with a radar system. This is a decision-making problem, and it is performed through a hypothesis-testing procedure.

Adaptive radar pulse detection design based on difference of box filter
IET Radar, Sonar & NavigationPrecise radar pulse detection is the premise of electronic support measures. A constant false alarm rate (CFAR) detection algorithm based on difference of box (DOB) filter is proposed to realise low‐complexity and environment‐adaptive radar pulse ...

CFAR Different Schemes Behavior and Detection Performance of Moving Targets
, 2004 In this paper detection probability of different CFAR schemes CA, GO, SO, and OS-CFAR is computed via various values of false alarm probability. The CA-CFAR and GO-CFAR detection performance is superior over other schemes; OS-CFAR detection performance ...
