One of the two channels was very stable in frequency: it was locked to an on-board ultra stable oscillator (USO).(More)
The paper describes how an activity is going on for a design, development and realisation of a large 12-meter deployable reflector antenna for space applications. The reflector antenna system is subject of an ESA contract awarded to Alenia Spazio as a prime contractor. The Russian company NPO EGS is responsible as sub-contractor for an important element,(More)
The paper presents the design and validation of a dual band feed system for the reflector antenna of the CoReH2O (Cold Regions Hydrology High-resolution Observatory) SAR instrument, investigated under ESA contract. The antenna is a dual linearly polarized single-offset reflector, illuminated by two side feed arrays operating in X and Ku band respectively.(More)
