DATA_SET_TERSE_DESCRIPTION
DATA_SET_DESCRIPTION Data Set Overview : This data set consists of a series of images of the Moon showing radar scaled echo power. Each covers about 400 square kilometers of the lunar surface, and contains two co-registered images. Transmitted signal was right-circular polarization, images are therefore left-circular and right-circular. Images are projected as Mercator maps for latitudes less than 16 degrees, Lambert (small-angle cone) between 16 and 48 degrees, Lambert (large-angle cone) between 48 and 80 degrees, and polar stereographic between 80 and 90 degrees. Processing Level Id : 4 Software Flag : N Processing Start Time : 1968 Processing Stop Time : 1990 Parameters : Data Set Parameter 'RADAR SCALED ECHO POWER' -------------------------------------------- Power of the backscattered echo, received at antenna scaled using some procedure, e.g., scaled to fit within an output dynamic range such as an integer value. Data Set Parameter Name : RADAR SCALED ECHO POWER Data Set Parameter Unit : DIMENSIONLESS Sampling Parameter Name : PIXEL Sampling Parameter Unit : N/A Minimum Sampling Parameter : N/A Maximum Sampling Parameter : N/A Sampling Parameter Resolution : N/A Sampling Parameter Interval : N/A Minimum Available Sampling Int : N/A Noise Level : N/A Source Instrument Parameters : Instrument Host ID : HSTK Data Set Parameter Name : RADAR SCALED ECHO POWER Instrument Parameter Name : RADAR ECHO POWER Important Instrument Parameters : 1 Measurement Information : Atmospheric Conditions ---------------------- NOT APPLICABLE Source ------ The radar observations were made using the Haystack radar and post-processing system. See ZISKETAL1974 for details. Calibration Standard -------------------- NOT APPLICABLE Wavelength Calibration ---------------------- The transmitter frequency is calibrated with a hydrogen maser.

CONFIDENCE_LEVEL_NOTE Overview : Images have been corrected for radar system parameters, lunar surface projection parameters, and mean lunar scattering laws. Data in different images should therefore depend on lunar surface scattering properties only, except for variations of radar echo power as a function of local surface tilt.
