The European Space Agency’s Planck satellite was launched on 14 May 2009, and surveyed the sky stably and continuously between August 2009 and October 2013. The scientific analysis of the Planck data requires understanding the optical response of its detectors,…

This paper describes a new integrated RF design tool for analysis and optimisation of reflector-based multibeam antenna systems. The new tool combines several powerful algorithms into a flexible software framework that allows end-to-end optimisation of antenna systems comprising of passive…

Shaped surface reflector antennas are the preferred antenna type when a contoured beam illuminating a service region on the Earth from a communications satellite shall be achieved. The size of the reflector aperture (relative to the wavelength) determines the level…

10 m reflector antenna for a conicalscan passive microwave radiometer in C band is proposed. The reflector is an offset paraboloid in light mesh technology excited in a multi-feed-perbeam configuration, so far never used in Earth observation missions. The instrument…

In this work we describe the design and operation of a scatterometer to be used at the European Space Agency. The instrument has the purpose to characterize smooth as well as rough materials, in transmission and reflection in the 50-750…
