WebbThe radar-return signals from the SEASAT synthetic aperture radar (SAR) were transmitted to the ground by means of a unique analog data link. The data link translates the 19-MHz radar spectrum from 1275 MHz to a downlink frequency of 2265 MHz and encodes the radar timing signal so that it can be overlaid on the downlink-signal spectrum.
