    Reprocessing of frames obtained of Seasat spacecraft in 2008.
    There is clear improvement thanks to my progress in processing
    over the past 2 years.

    Now also, I made work of analysing the details and spent some time comparing
    them to different images and drawings. What I already knew earlier, is that
    the prominent bright beam visible in the images is the main body. The obvious
    visible panel must be the Synthetic Aperture Radar (SAR), the first spaceborne 
    SAR in history.
    
    Comparing different frames, it became clear, the solar panels which are on the
    other side of the main body are in this image invisible because they are
    probably edge-on or near edge-on. In some other frames the panels, just 
    became visible, but these frames were not as good as this one.
    The other structures on the side of the SAR can be interpreted as some
    of the antennae on that side:

    The sat seems to fly in XPOP mode (the line through the main body is 
    perpendicular to the orbital plane). The image you see, is made 
    after culmination as it appeared the different antennae and panels
    were best visible then, during this pass.
