Orbit Prediction Errors Resulting from Vertical Misalignment of a Radar Antenna.

Abstract

Accidental misalignment of an antenna's vertical reference axis with respect to the local vertical introduces errors into the measurements of azimuth and elevation directly. If corresponding corrections are neglected, relatively small misalignments can prevent a radar from achieving high-accuracy orbit-determination. The use of electronic level-sensors for making such corrections in real-time is described. Some numerical examples are presented to illustrate the problem. (Author)
