Data Set Overview : Radar scaled backscatter cross section images of the Moon made with the 12.6 cm wavelength radar at Arecibo Observatory. The data are corrected for antenna beam shape, but not for radar scattering variations with incidence angle. Data are scaled to fit within dynamic range of output values. The images are projected onto a Mercator grid with a longitude spacing of 0.01 degrees per pixel.   Processing Level Id : 5 Software Flag : N Processing Start Time : 1986 Processing Stop Time : 1990   Parameters :  Data Set Parameter 'RADAR SCALED BACKSCATTER CROSS SECTION' ----------------------------------------------------------- Cross section values that are scaled by some procedure, such as dividing by theoretical or empirical scattering laws.
