Microwave Glide Slope System Engineering Model.

Abstract

The report describes the development of an L-band, 1585-MHz (microwave) glide slope system, complete with monitoring capability, that is fully compatible with the existing UHF glide slope system. To accomplish this, it was necessary to develop and fabricate two slotted waveguide antennas (24 and 32 feet), solid-state transmitter/modulator components, an aircraft frequency converter and an antenna unit. This system was tested at two Greater Pittsburgh problem sites and at NAFEC, and was found to have good course quality with each of the antennas. However, the 32 foot antenna was best suited to the lower glide slope angles of 2.5 to 2.7 degrees and the 24-foot antenna for the 2.7 to 3.0 degree path angles, in terms of below path clearance.
