A Nonlinear Transform-Based Variability Index CFAR Detector for Doppler-Extended Targets [PDF]

open access: yesSensors
In frequency-modulated continuous-wave (FMCW) radar systems, the detection of Doppler-extended targets (DETs) is a critical challenge. The micro-Doppler effects induced by the motion of extended targets such as pedestrians cause the echo energy to spread

A constant false alarm rate (CFAR) detector for RADARSAT-2 along-track interferometry

open access: yesCanadian Journal of Remote Sensing, 2005
Canada's RADARSAT-2 synthetic aperture radar (SAR) satellite will be equipped with an experimental ground moving target indication (GMTI) mode, which makes use of the "dual-receive" capability of the RADARSAT-2 antenna to provide two apertures aligned in the along-track direction.

A False Alarm Elimination Algorithm of Foreign Objects Debris Detection Based on Duffing Oscillator

open access: yesIEEE Access, 2022
The main challenge of foreign objects debris (FOD) monitoring based on millimeter-wave (MMW) radar is the interference of strong ground clutter. The clutter-map constant false alarm rate (CM-CFAR) method is commonly utilized for FOD monitoring, but ...
