DATA_SET_DESCRIPTION 
Data Set Overview
    =================
      Backscatter image data of the Moon made with Arecibo 70 cm
      radar in 1986 and 1987.  The observations were made to
      demonstrate mapping resolution of 0.5 - 1.0 kilometers by using
      short transmitter pulses and long integration times (up to 8
      minutes).  Image pixel values are in proportion to raw power in
      delay-Doppler sampling coordinates.

Overview
    ========
      No correction has been made for antenna beam, scattering area
      or scattering law.  Thermal signal-to-noise varies across the
      image.  Note that thermal noise samples are in the first set of
      lines.
