RADAR ASTRONOMY AND PROPAGATION RESEARCH.
Abstract
Research in this report and application of radar astronomy techniques for study of the solar corona, interplanetary gas density, ionospheric electron content, and cislunar gas density. It included: (1) completion of the 300-kw transmitter and log-periodic antenna array for solar and lunar radar work; (2) attempts to reestablish radar contact with the solar corona, including development of pseudo-random coding and cross correlation techniques for optimizing ranging information and detection; (3) intensive study of the polarization, strength, and doppler excess of moon reflected signals to obtain ionospheric electron content, scintillation information, and rate of change of electron content over the earth-moon path as a function of time; (4) daily measurements of the total ionospheric electron content using Faraday rotation differences between two closely space frequencies reflected from the moon; (5) development of computer methods for sampling and digitizing analog moon data recorded on magnetic tape; and (6) theoretical studies of the scattering from, and transmission through, plasmas as applied to the density and constitution of interplanetary gas and planetary ionospheres. Much of the experimental program was made possible by the availability of unique and extensive radar facilities acquired and constructed under this contract. (Author)
