METHODOLOGY FOR VERIFICATION OF SPHERIACAL RADIOTELESCOPE SURFACE ADJUSTMENT RESULTS

Abstract

The spherical antenna adjustment is the procedure which starts with the identifica­tion of the difference between the antenna’s geometric and electrical axis. Misalignment of the axis is generally caused by antenna reflector surface roughness. In this paper, the methodology of ROT-54/2.6 radio telescope’s antenna surface roughness estimation is studied. The methodology can be used as a verification mechanism for the adjustment already done. A laser rangefinder is considered as a measuring device for that purpose.
