Probability of detection for a GO CFAR radar processor using envelope detection approximation

open access: yes, 1994
The greatest-of logic for a constant false alarm rate processor (GO CFAR) is a commonly used method for the adaptive setting of a radar detection threshold in the presence of clutter edges. Instead of using a true envelope detector x = I2 + Q2, which is difficult to implement, envelope detection approximations of the form Xe = aMax (I),(Q) + bMin (I ...
