Abstract:

Research pinpoints techniques promise improvement in aircraft hf communication system design. Approaches discussed in the report include adaptive hf antenna array indlucing antijam, miniature passive and active antenna elements, adaptive phase equalizationpredetection combining, polarization diversity, mode averaging diversity combiner, and antenna methematical modeling techniques. Two techniques show promise for diversity reception -- Villard mode averaging and predetectionphase equalization combining. Improved aircraft antenna systems are the key to improved aircraft communications. Mathematical modeling shows promise for designing aircraft antennas. Hf adaptive antennas may be feasible for both beam and null steering.
