Description
The objective of the activity is to study the Ka-band antenna subsystem for an interferometric SAR instrument utilising scan-on-receive technique. The activity includes the review and selection of a SAR instrument concept, design and analysis (RF, accommodation, mechanical, thermal, thermo-elastic) of the antenna subsystem, including the radiating apertures for both the Tx and Rx operations of the instrument, the corresponding passive RF feeding systems of the antennas, the antenna structures/supports, the deployment arms interconnecting the antenna to the host S/C, the HDRMs, the deployment and pointing mechanisms. A breadboard of the identified most critical component of the subsystem, identified in the RX feed array and the relative scan on receive BFN, provides the proof-of-concept.
