Performance evaluation of CA-, GO- and SO-CFAR processors in a non-centered Lévy-distributed clutter
Majlesi Journal of Electrical EngineeringConstant false alarm rate (CFAR) processors are critical for radar reliable target detection in radar systems. Traditional CFAR designs often assume Gaussian clutter, which may not reflect real-world conditions.

Sonar false alarm rate suppression using classification methods based on acoustic modelling [PDF]
, 2011 The use of high–resolution, active sonar systems in littoral environments often results in high false alarm rates. False alarm rate inflation (FARI) and non–Rayleigh reverberation (NRR) are two well–documented causes.
