Analyzed 13-cm and 116-cm Bistatis Radar Lunar Observations


Availability: At NSSDC, Ready for Offline Distribution (or Staging if Digital)

Time span: 1971-08-01 to 1971-08-01


This data set, referred to as the integral tapes by the experimenter, is a complete set of analyzed data records derived from the reduced data records (or JM Doptrack tapes, data sets 71-063A-014A and -14B). This data set was received from the experimenter and is on binary magnetic tape in XDS Sigma 5 machine images. The data contain certain properties of the reduced data as well as inferred properties of the lunar surface. Each tape file is composed of 1 header record followed by many data records. Each header record contains a file identifier, the date the data were taken, the time increment between the midpoints of each data averaging frame, and the number of data records following the header record. Data records list the polarized power, normalized polarized power, unpolarized power, equivalent area bandwidth, normalized absolute moment bandwidth, normalized second moment bandwidth, centroid of the echo spectrum, rms slope inferred from equivalent area bandwidth, handscaled 1/2 power echo bandwidth, a data validity flag, spacecraft antenna gain (or 0), and all the ephemeris and ancillary data contained on data record 6 in each data frame of the reduced data tapes (data sets 71-063A-14A and -14B).
