چکیده

Detection of the range spread target in high resolution radar (HRR) is studied and a novel method based on scattering centers with high entropy in complex white noise is proposed. The proposed detector uses two-threshold strategy. The first threshold determines high entropy centers of the target then, these centers are used in a GLRT test to decide about presence of target. It is shown that the proposed detector can estimate the variance of background noise so it exhibits a CFAR property.
