MODELS REPRESENTATION SIGNAL IN THE PROCESSING OF INFORMATION IN SMALL BASIC POLARIZING MEASURING SYSTEM
With the development of radar technology, in modern conditions, MIMO systems become more relevant. The main principle functioning of such systems is the ability to scan the same object with several radars, or several radar positions that are separated from each other at a distance. In this case, the processing of signals reflected from an object consists not only in determining the coordinates of objects , but also in using correlations between the reflected signals, in order to obtain additional features for detecting and recognizing objects. Variants of such systems, which have polarizing differences in the radiated and received signals, have not yet been sufficiently studied. The article considers the structure and principles of functioning of a small basic polarization measuring system. Mathematical expressions are obtained for describing the signals emitted and received reflected from objects by two separated positions operating on orthogonal polarizations. Expressions describing the voltage at the output of the receiving channels of a small basic polarization measuring system, with full polarization sensing, for the formation of a polarizing scattering vector of the object are obtained. The obtained expressions were analyzed and the signal parameters affecting further processing were determined.
