Abstract:

Two new analog-type monitors were designed, built and tested for the purpose of providing a reliable, and accurate representation of the ILS localizer signal as seen by an aircraft flying on an approach. One monitor involves detector pickups at the radiating antenna elements and the other uses seven directional elements located 300 feet in front of the localizer array. Both monitors are designed to give quantitative representations of conditions in the far-field which are generated by a wide aperture source. Mathematical models are described which are to be used for predicting effects on localizer path due to large reflecting surfaces such as hangars and large aircraft. From these models information can be derived as to the most critical placement of the reflecting surfaces. Calculations and discussions of the anomalous behavior of the glide paths at San Francisco, and Oakland, California are presented. Author
