Abstract
It is known that one of the most complicated problems in radar direction finding is the problem of an effective detection and recognition of objects, especially fixed ones. In the paper it is shown that one of the promising approaches for solution of the problem lies in use of polarization parameters of radar-tracking signals. The results of analysis of radiation scattering by objects confirms that the polarisation characteristics can bear extensive information both about object parameters and about its operation. It is established that the polarization characteristics of objects at the specific frequency of exploration and fixed direction of observation can be given by five material parameters (Hujnen's descriptors). In the paper the expressions for calculation of five descriptors are derived and the theoretical investigation on evaluation of possibility of small-size ground object detection based on polarization properties using polarization parameters vector was carried out.
