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 in-phase (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. Closed-form expressions which describe the FD performance are given and their accuracy evaluated.
