Abstract
The singularities of processing the radar information using the signals of dual orthogonality, i.e., dually polarized signals have been considered. Several methods of shaping the dually polarized signals have been described. The potential resolution properties and energy characteristics of the system during the multiplicative signal processing have been considered in terms of properties of the uncertainty function of these signals. The enhancement of radar system resolution in case of multiplicative unification of polarization-orthogonal channels after the optimal signal processing has been demonstrated. The estimation procedure for the object scattering matrix elements after compression of orthogonal components of a signal has been considered.
KEY WORDS: radar system, polarization modulation, signals of dual orthogonality, polarization scattering matrix, multiplicative processing and resolution
