A space-borne antenna system includes a number of panels being moveable to each other and having a gap in between them when the panels are arranged in an operation condition. The system also includes an RF distribution network for providing transmit signals to the number of panels and combining received signals from the number of panels. The system further includes a set of choke flange assemblies that allow a contactless inter-panel signal transmission across a dedicated gap. A respective choke flange assembly is arranged on the far side of a radiating surface of the dedicated adjacent panels. The system also includes an RF seal assembly for suppressing a signal coupling of signals radiated from the number of panels to the set of choke flange assemblies by sealing the gap.

Space-borne antenna system

A method of radar measurement by transmitting and receiving radar signals with at least two spatially separated radar systems. The method further includes exchanging reference radar signals between the at least two radar systems to determine measurement-relevant parameters. Moreover, a determination of at least one of a relative phase relationship of the reference radar signals of the radar systems and a relative time position of time references of the radar systems is based on reference radar signals received. The instant abstract is neither intended to define the invention disclosed in this specification nor intended to limit the scope of the invention in any way.
