INVESTIGATION OF A TIME-FREQUENCY TECHNIQUE FOR RANGE AND RANGE-RATE MEASUREMENTS.

Abstract

A flyable breadboard device utilizing a stable atomic clock to derive range and relative closing speed of two aircraft was built by National Company, Incorporated, and was installed aboard two Federal Aviation Agency aircraft. The ratio of range and relative closing speed is used to approximate time to nearest approach (tau) for assessing collision threats. An analysis of the results indicated that the technique is a feasible method of determining range and relative closing speed (rangerate) and is applicable to assess airborne collision threats.
