CFAR
Constant False Alarm Rate, a radar target detection method that adaptively sets a threshold based on local background estimation, maintaining a constant probability of false alarm. CFAR detectors estimate the noise and clutter level from surrounding cells and adjust the detection threshold accordingly, ensuring stable detection performance under varying interference conditions.
Timeline (last 90 days)
Traditional clutter suppression methods include moving target indication (MTI), constant false alarm rate (CFAR) detection, and subspace-based methods (such as eigenvalue decomposition and MUSIC).
Constant False Alarm Rate (CFAR) detection adaptively sets the detection threshold under conditions where the statistical properties of the noise background are unknown or changing, maintaining a constant false alarm probability.
