Abstract

The synthetic discriminant filter (SDF) is a linear combination of the target and the objects to be rejected. The coefficients of the combination are calculated in such a way that the central correlations with the different objects take predeterminate values. Nevertheless, The correlation values in other points are not controlled, and in consequence, high sidelobes may appear causing false alarms. In this communication we propose a method to solve this problem. The procedure is based on the use of two filters and the subsequent postprocessing of the correlation intensity distributions obtained.
