Features of measured scattered spectrum of a metal plate which
one part is covered by a resonant radio absorbing material are considered. At
the transition through resonance frequency of the cover the phase of reflected
signal is changed leading to fast change of indicatrix of scattering. It is
shown that for such object on frequencies near to resonant, sidelobe levels can
be higher than level of mirror reflexion.
Keywords: scattered spectrum, resonant radio absorbing
material.
