A Short Range, High Accuracy Radar Ranging System,
Abstract
This paper described the design and test of a low power, highly accurate FM-CW radar ranging system. The objective of the design wad to provide an inexpensive aircraft-to-aircraft ranging system with + or - 1 foot accuracy at ranges up to 400 feet. Particular detail is given to describing the design and test frequency tracking circuit. Quartz crystals were used to make the narrow bandpass filters necessary for good frequency resolution. The design of the rest of the system was kept simple by using standard electronic test equipment. The system was tested for its range accuracy and range resolution capabilities. The results show that the system was limited by ground clutter and the performance of the test equipment available. However, given the right equipment in an airborne environment the accuracy desired for the system is possible. Originator-supplied keywords include: Radar tracking, Range finding, and Short range.
