Multipath Environment Evaluation.
Abstract
This report describes an experimental program aimed at evaluating the multipath environment typical of that which will challenge C-band microwave landing systems. The report describes the ground and air testing conducted in the Area B complex of Wright-Patterson Air Force Base, Ohio, and includes a wealth of data gathered with the aid of MLS hardware used on the prior phase of this program. A substantial fraction of the effort was devoted to measurements made on a large reflecting screen used by FAA in the test phase of Phase II of the National Landing Plan. It is concluded from the data gathered at Wright-Patterson AFB, that multipath signals generated by the use of the screen in isolation (as at NAFEC and Wallops) are quite dissimilar to those observed from real-life structures in their spatial characteristics. It is further concluded that typical hangars have quite similar reflection characteristics, almost independent of their constructional details.
