%A Friedt, Jean-Michel %D 2021 %T Sentinel 1 raw IQ stream processing beyond Synthetic Aperture RADAR applications %K %X A free, opensource Sentinel1 Level0 decoder is described providing access to the raw IQ data transmitted by the spaceborne RADAR satellites prior to range and azimuth compression. Most importantly, rank echoes when emitted pulses have not yet returned to the spaceborne RADARs allow for listening to ground based emissions – most significantly civilian (weather) and military RADARs, as well as for radiometric measurements. %U https://pubs.gnuradio.org/index.php/grcon/article/view/106 %J Proceedings of the GNU Radio Conference %0 Journal Article %V 3 %N 1 %8 2021-07-03
