CFARdetector derived from correlation processing in adjacent range bins
Abstract
It is suggested that noncoherent radar in conjunction with a device which measures the correlation coefficient in adjacent range bins could be used as a detector which differentiates between discrete target returns and noiselike returns by means of signal fluctuation patterns. This detector would respond with a constant falsealarm rate (CFAR) to noise and diffuse scatterers. A computer simulation study indicates that the correlation detector is capable of sifting out a small useful signal from noise and is unaffected by bursts of random noise even if the noise intensity changes suddenly. The calculation procedure for determining the probability of detecting a discrete signal is explained.
