Antenna models relating voltage excitations to radiated fields are an important part of any electromagnetic measurement, with applications ranging from two-way communication systems to full-wave inverse scattering. Here, we derive a two-antenna model relating the multipole expansion of the fields radiated and received by antennas to S-parameter measurements between them. We also show how to determine...
The full-size VHF/UHF antenna feed array prototype for the MOSS radar antenna system was successfully built and tested. The validity of the design and feasibility of constructing such a feed system for a future spaceborne radar that has a 30-m mesh reflector antenna was demonstrated. No road blocks or major remaining challenges were identified, though several potentials for improvement were identified...
