| Abstract | Results of aeronautical L-band multipath channel characterization tests are given. All tests were conducted between September 1974 and April 1975 as part of the U.S. DOT aeronautical technology test program. These tests were part of the international Integrated ATS-6 L-Band Experiment coordinated by the NASA/Goddard Space Flight Center. Wideband PN-coded test signals transmitted from an FAA KC-135 jet aircraft were relayed by the ATS-6 satellite for reception by the satellite aeronautical channel prober (SACP) receiver located at the NASA/Rosman ground station. Both oceanic and overland multipath data are analyzed to provide delay-Doppler characterizations of the channel. Specific anlaysis outputs presented include the delay-Doppler scatter function, delay spectra, Doppler spectra, frequency and time autocorrelation functions, spread parameter measures, total scattered intensity and time-domain statistics. Oceanic results are compared to expectation through the use of physical optics surface integration vector scatter model. Results are presented for a variety of aircraft/satellite geometries, signal polarizations, and terrain states. The report consists of seven volumes: I-Executive Summary; II-Demonstration of Satellite-Supported Communications and Surveillance for Oceanic Air Traffic Control; III-Summary of U.S. Aeronautical Technology Test Programs; IV-Data Reduction and Analysis Software; V-Multipath Channel Characterization Test; VI-Modem Evaluation Test; VII-Aircraft Antenna Evaluation Test. |
