Abstract

Methods of external calibration of radar polarimeters are considered. Algorithms for evaluating elements of the Mueller matrix and eliminating distortions introduced by the polarimeter are presented. The article describes the design of a radar reflector with electrically controlled polarization properties that can imitate the properties of two and three-sided reflectors and non-reciprocal reflectors. The analysis of the mode of dynamic switching of the scattering characteristics of the reflector used for calibration by the method of polarization modulation of scattered signals is performed. The results of experimental studies of a laboratory sample of a radar reflector with controlled characteristics are presented. The results obtained can be used in radar.
