Abstract

A system for measuring azimuth angle of a target (meteor trail at height of 80 to 110 km) is described. The system is part of a larger system that uses pulsed radar to determine doppler shift, slant range, elevation angle and antenna boresight information for each meteor trail recorded. The angle measuring system uses the technique of radar interferometry (thus depending on phase measurements), which has the advantages that the uncorrelated receiver noise is averaged out, increased angular resolution is obtainable, and calibration of the system is much easier than with systems which depend on amplitude measurements. Data are presented which verify the system operation.
