Abstract:
The BIOMASS SAR P-Band antenna consists of a large deployable reflector antenna system with an offset geometry that results in high crosspolar level from the reflector, this is compensated with an adequate design of the reflector Feed S/S to generate a “crosspolar” pattern with proper amplitude and phase to cancel the reflector crosspolar down to admissible values. In the frame of BIOMASS mission the contract “Large Antennas for PBand SAR Critical Breadboarding” is running between ESA and CASA for the development of an engineering model of the Feed S/S. The work developed under this contract is presented in this paper.
