The analysis of the long-term stability of the scattering properties of various types of natural covers was carried out using Japanese PALSAR-1 and PALSAR-2 spaceborne synthetic aperture radar observations. High stability of the reflective properties of the extended objects of the Antarctica and South America, comparable with stability of specialized artificial targets, has been revealed. For that reason, distributed targets under discussion may be considered as suitable targets for spaceborne radars intercalibration and monitoring of their stability.
