NSSDC_DATA_SET_ID
DATA_SET_TERSE_DESCRIPTION
DATA_SET_DESCRIPTION Data Set Overview : This data set consists of a VICAR2 format image of Venus large-angle radar backscatter cross section, from the side-looking mode of the Pioneer Venus radar mapper experiment. The cross section is corrected for Venus atmospheric absorption and normalized to 45 degree incidence angle via the phenomenological Muhleman scattering function. Data are presented in simple cylindrical format, with 1024 lines (latitude) and 4096 samples (longitude). Processing Level Id : 5 Software Flag : N Processing Start Time : 1988-12-01 Processing Stop Time : 1988-12-01 Parameters : Data Set Parameter 'RADAR BACKSCATTER CROSS SECTION' ---------------------------------------------------- Cross section values are dimensionless and correspond to the projected area of a sphere that would produce the observed backscattered power, divided by the scattering area, i.e. the pixel area. Data Set Parameter Name : RADAR BACKSCATTER CROSS SECTION 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 : P12 Data Set Parameter Name : RADAR BACKSCATTER CROSS SECTION Instrument Parameter Name : RADAR ECHO POWER Important Instrument Parameters : 1 Processing : N/A
