Description
Summary:This paper presents the principle, design, and measured characteristics of a 90-degree polarization-rotating Van Atta array reflector with suppressed scattered field as a reference target for polarimetric radar calibration. A polarimetric calibration method that uses a trihedral and the present reflector needs no assumptions on scene characteristics and statistics and no independent phase calibration
