Suppression of Weibull Radar Clutter
Summary :
Weibull-distributed clutter are reviewed. Most of the clutter received by L, S, C, X and Ku band radars obey Weibull distribution. Clutter suppression techniques for Weibull clutter are also reviewed. Especially, the generalized Weibull CFAR detector is emphasized. The approch is to estimate the shape and scale parameters of the Weibull clutter using order statistics and then use them in the detector. The generalized CFAR detector transforms the Weibull clutter distribution into a normalized exponential distribution. When a target is present, the transformation produces a large error that can be used to detect the target. Actual data taken by a Ku band radar are used to compare the proposed method with another method to estimate the Weibull parameters and with the Weibull CFAR detector. Order statistics estimation requires a small number of samples and can be used to find the local value of Weibull clutter parameters and, thus, the proposed method requires less computational time to find the Weibull parameters.
