All-Weather, Low-Level Navigation and Implementation of a One-Way Ranging, Range-Range Navigation System.

Abstract

The report contains a synopsis of a six and one-half year effort in research and development activities in low-level, all-weather aircraft navigation. Background work is described leading to the successful flight test of the low frequency direct ranging range-range navigation system developed. Theory of the TRF MLE receiver processors used in the tests is discussed and future developments suggested. A learning version of the processor using a priori information is discussed and methods for making the processor adaptive are outlined. Airborne phase measuring techniques have been investigated. Both analog and digital as well as mixed methods are considered. A digital local oscillator for a projected superheterodyne model is studied. Work on auto-correlation and statistical data collection is reported. (Modified author abstract)
