    Last update: 10 April 2017

    This SAR Level 0 product is acquired in Image Mode. The products consist of the SAR telemetry data and are supplied as full Level 0 segments, unprocessed. It also contains all the required auxiliary data necessary for data processing.

    The product serves two main purposes:

    • For testing ERS SAR processors independently from the HDDR system
    • For users interested in full SAR data processing.
    Product characteristics
    Scene area 100 km (range - across track) x full segment length (azimuth - along track)
    Scene size 5616 samples (range) x full segment length (azimuth)
    Pixel depth 10 bits signed integer (5 bits I, 5 bits Q)
    Projection Slant range
