Abstract : The report presents results of theoretical and experimental study of a new type of VOR, which has been named 'Square Wave' VOR (SVOR) because its variable phase waveshape is roughly square. Two experimental SVORs have been built and tested. The second one was built under FAA contract and was extensively ground and flight tested at both NAFEC and Ohio University. Results of these tests are reported. Tests of a number of receivers for compatibility with SVOR signals were made, and the results are presented. A theoretical and experimental investigation of VOR and SVOR errors caused by Doppler shift in a multipath carrier is included. A feasibility study of a wide aperture SVOR designed for a 13 times reduction in multipath is presented. (Author)
