Introducing Switching Ordered Statistic CFAR Type I in Different Radar Environments
EURASIP Journal on Advances in Signal Processing, 2009 In this paper, a new CFAR detector based on a switching algorithm and OS-CFAR for nonhomogeneous background environments is introduced. The new detector is named Switching Ordered Statistic CFAR type I (SOS CFAR I).

Modified Anderson-Darling Test-Based Target Detector in Non-Homogenous Environments
Sensors, 2014 A constant false alarm rate (CFAR) target detector in non-homogenous backgrounds is proposed. Based on K-sample Anderson-Darling (AD) tests, the method re-arranges the reference cells by merging homogenous sub-blocks surrounding the cell under test (CUT)

An approach of constant false alarm ratio for improved target tracking [PDF]
Scientific Technical Review, 2020 Each radar has the function of surveillance of certain areas of interest. In particular, the radar also has the function of tracking moving targets in that territory with some probability of detection, which depends on the type of detector.

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

International Journal of Gynecology &Obstetrics, EarlyView.Abstract Background Prior cesarean delivery (CD) is a leading indication for repeat CD and a key driver of rising cesarean rates in Sub‐Saharan Africa. Evidence on associations between prior CD and adverse outcomes in low‐resource settings remains limited.
