Abstract : The greatest of constant false alarm rate processor (GO CFAR) is a useful architecture for adaptively setting a radar detection threshold in the presence of clutter edges. The GO CFAR input is often the envelope detected inphase (I) and quadrature (Q) channels of the baseband signal (x,  sqrt (I2 + Q3). This envelope detection can also be appropriated using x=aI+blQ which requires less complex hardware (a and b are simple multiplying coefficients). The envelope GO CFAR processor and several envelope approximation GO CFAR processors are compare in terms of the probability of detection (PD) performance. Closedform expressions which describe the FD performance are given and their accuracy evaluated.
