SENTINEL-1 HRM SHOCK PROPAGATION

摘要

The Sentinel-1 SAR instrument is fixed by 12 identicalrnHRM units, preloaded with 30 kN each. Though therndesign is based on several Astrium heritage programs,rnhigh frequency release shocks turned out to be a majorrnissue in this special application due to the vicinity ofrnsensitive electronics. The paper describes the results andrnlessons learned of an investigation about emitted highrnfrequency release shocks performed in the frame of thernqualification process of the Sentinel-1 HRMs.
