| 摘要： | This technical note describes Microwave Landing System (MLS) and Precision Distance Equipment (DME/P) mathematical modeling performed for runway 19L, Andrews Air Force Base (ADW), Camp Springs, Maryland. This study evaluates the effects of scattering and shadowing from selected buildings, hangars, aircraft, and terrain. Results are provided as plots illustrating the predicted multipath levels, separation angles, and the resulting error plots from the worst case contributors. Scenarios were modeled to determine the effects of the multipath sources in the modeled environment. These resulting errors were analyzed and compared to error tolerance (FAA-STD-022d) to determine if the errors are acceptable. The effects of the ADW environment were analyzed and evaluated. It was determined that the proposed site will perform satisfactorily with no changes. |
