Average values of the invariant polarization parameters for scattering by compound objects

The problem of analytical calculation of average values of the invariant polarization electromagnetic field parameters is considered for scattering by a compound object comprising an artificial small-sized object and underlying surface with a considerable number of centers of secondary scattering. The main difference of this work from the results obtained by W. Boerner, E. Pottier, and S. Cloude [1–3] and other researchers is efficient application of polarization invariants of radar objects that can be measured in real time and displayed on a radar monitor. The application of these invariants allows the radar image contrast to be improved significantly and the probability of detection of small-sized objects against the underlying surface background to be increased.
