Abstract:

The Watertown Arsenal Building No. 311 was evaluated for use as an indoor Instrument Landing System ILS model range using upward frequency scaling of 100 to 1. To model the effects of small buildings and aircraft in the vicinity of an airport ILS, any model range has to have very low background reflections. If background reflections are large, they will obscure the desired measurements. Sets of measurements designed to determine the amplitude and location of undesirable background reflections due to structural objects around the proposed model site show that it will be necessary to completely enclose the range with high quality absorber.
