Abstract

Millimeter wave passive radiometric imager based on frequency scanning antenna is suggested. As a frequency scanning antenna, the periodically perturbed dielectric image waveguide is considered. In frequency range 30÷38 GHz, the scan of the main lob over 40° has been realized. Parallel multibeam forming is realized by means of the set of narrow bandwidth resonant modulators, each of them controlled by the own modulating frequency.
