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.", "identifier": "urn:nasa:pds:context_pds3:data_set:data_set.arcb-l-rtls-4-70cm-v1.0_uden-f4eu", "issued": "2018-06-26", "keyword": ["moon", "pre-magellan"], "landingPage": "https://pds.nasa.gov/ds-view/pds/viewDataset.jsp?dsid=ARCB-L-RTLS-4-70CM-V1.0", "modified": "2025-07-17", "programCode": ["026:005"], "publisher": {"@type": "org:Organization", "name": "National Aeronautics and Space Administration"}, "references": ["https://pds.nasa.gov"], "theme": ["Earth Science"], "title": "ARECIBO MOON RADIO TELESC RESAMPLED 70 CM RADAR MOSAIC V1.0"}
