PDS Information
Find a Node - Use these links to navigate to any of the 8 publicly accessible PDS Nodes.

This bar indicates that you are within the PDS enterprise which includes 6 science discipline nodes and 2 support nodes which are overseen by the Project Management Office at NASA's Goddard Space Flight Center (GSFC). Each node is led by an expert in the subject discipline, supported by an advisory group of other practitioners of that discipline, and subject to selection and approval under a regular NASA Research Announcement.
Data Set Information
DATA_SET_NAME ARECIBO MOON RADIO TELESC RESAMPLED 70 CM RADAR MOSAIC V1.0
DATA_SET_ID ARCB-L-RTLS-4-70CM-V1.0
NSSDC_DATA_SET_ID
DATA_SET_TERSE_DESCRIPTION
DATA_SET_DESCRIPTION Data Set Overview : High resolution radar map compiled from measurements made between 1981 and 1984 with the 70 cm wavelength radar at Arecibo Observatory. The data have resolutions ranging from 2 to 5 kilometers. The pixel spacing is 0.1 degrees in latitude and longitude. The point at line 1000 and sample 1000 corresponds to 0 degrees latitude and 0 degrees longitude. The pixel values are scaled to represent 20 * log10 (backscattered power). Observed power has been corrected for antenna beam, scattering area and scattering law. Observed power of 1000, which is the lunar average, thus has a value of 60 in the data set. Radar was transmitted in left-hand circular polarization, and both right-hand circular polarization (i.e. polarized) and left-hand circular polarization (i.e. depolarized) echoes were received. Processing Level Id : 4 Software Flag : N Processing Start Time : 1981 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 : UNK Source Instrument Parameters : Instrument Host ID : ARCB 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 ------ Radar pulses were transmitted using the high power 430 MHz transmitter at Arecibo Observatory. See THOMPSON1987 for details. Calibration Standard -------------------- NOT APPLICABLE Wavelength Calibration ---------------------- Transmitter frequency is calibrated with a hydrogen maser.
