NAVTOLAND Microwave Scanning Beam Tests at NOSC. Three Landing Guidance Systems Tested in a Specular Multipath Environment.

Abstract

Results of testing Ku-band pulse-coded microwave scanning guidance system concepts are reported. Three different systems were tested under conditions of severe specular multipath. It is concluded that Ku-Band antennas with elevation and azimuth scanning beamwidths as wide as 4 and 6 deg, respectively, are adequate for shipboard landing guidance systems and that circular polarization and an elevation scan technique at low-angle-beam cutoff and mathematical beamfitting are effective solutions to multipath problems expected for a Navy shipboard system. Additionally, 1- and 2-microsec/deg coding was tested. No difference in accuracy was found. (Author)
