The Transportation Systems Center electromagnetic scattering model was used to predict the course deviation indication (CDI) at the Dallas/Fort Worth Airport in the presence of several derogating structures in the report FAA-RD-72-96 'ILS Localizer Performance Study Part 1 Dallas/Fort Worth Regional Airport and Model Validation-Syracuse Hancock Airport.' In this report the recommendation was made to use a capture effect system localizer. In the present report several additional structures, the Braniff and Delta hangar buildings, are modeled. Using the recommended capture effect localizer, it is found that these two additional structures do not add significantly to the derogation, and the category 1 and category 2 operation is still possible on the four instrumented runways tested.
Comparison is made of theoretically calculated and experimentally determined scattering from metallic tilted rectangles and vertical cylindrical scatt...
The construction of a mathematical model of The Instrument Landing System (ILS) multipath problem was undertaken. This report presents the theoretical...
