RADAR ANTENNA WITH DECREASED EFFECTIVE SCATTERING AREA

摘要

FIELD: radio engineering. ^ SUBSTANCE: in radar antenna containing at least one radiator operating within the specified working frequency band there arranged before radiators in one plane are frequency selection devices with band pass characteristics allowing to pass electromagnetic radiation in working frequency band, and to reflect the radiation beyond that band; before radiators at the specified distance there arranged is thin dielectric sheet with high dielectric permeability. ^ EFFECT: decreasing effective scattering area of antenna within its working frequency band. ^ 7 dwg
