This paper proposes a new adaptive suppression scheme for radar clutters. This scheme applies a multisegment MEM which has been known as a means for power spectral analysis and for classification of radar clutters. This adaptive suppression scheme is applied to the multisegment MEM based on the work by Zhang and Haykin who assumed that clutter data in neighboring range rings have a high correlation. Actual clutter data (ground, sea, and weather clutters) collected by an experimental L‐band radar with a low PRF wave were used. A comparison was made of performances based on improvement factors between the new suppression scheme for clutters and the suppression scheme used by Zhang and Haykin. The new processing method is shown to give an improved level by a few decibels for the numerical values of improvement factors. This was confirmed by the detection efficiency of an object signal which was buried in clutters using topological figures. It was clarified that the new suppression scheme for clutter possesses an enhanced capability in detecting the object signal easily compared with the method of Zhang and Haykin.
