Nonreciprocal retro-reflective array antenna

Scattering properties of various bodies in a radar wavelength range are investigated now, basically, for cases when conditions of the theorem of reciprocity are satisfied. Display of nonreciprocal properties of scattering medium in nature conditions occurs rather seldom. In these conditions, creation of the artificial radar reflectors having strongly pronounced nonreciprocal properties, allows to solve a problem of detection of the target by polarizing attributes on a background of spreading surface. This article considers the analysis of polarizing properties of the nonreciprocal reflector made in the form of short-circuited horn antenna, with the ferrite core placed inside.
