Abstract
This paper presents the method of radar observation of objects which are located in the zone of atmospheric formation (precipitation of the various phase states). The interconnection of the operational radar information is used and represented by the Stoke’s physical parameters. The Stoke’s physical parameters are characterized by the total reflecting properties of the object and atmospheric formation with Stoke’s parameters which are obtained in advance for a certain type of atmospheric formations and recorded in the radar observation database. The process of scattering of the irradiated wave on the observed radar object is represented by a model built on the concept of understanding the condition of the energy matrix. The energy matrix provides information about the parameters and properties of the scattering process under the conditions that parameters of the irradiation wave are known. The objects scattering ability is described by a radar scattering matrix when the object is irradiated by the electromagnetic wave with four polarizations and when an echo signal is received for each polarization of the irradiation wave. For each scattering object there is a strong temporary dependence of the elements of the matrix since the direction of irradiation of the object and the observation of the scattered wave are determined by the conditions of radar observation. The task of the radar observation of an object located in the atmospheric formation comes down to subtracting the energy matrices of the object plus the atmospheric formation and the atmospheric formation, as a result the energy matrix of an object is determined and its scattering properties are characterized. The optimization procedure of the electromagnetic wave received by the radar polarimeter antenna of an electromagnetic wave was reviewed using the Stoke’s vectors and Muller matrices.
