A STUDY OF ALIGNMENT ERRORS BETWEEN THE BEARING CURSOR AND ANTENNA TRACE ON THE PPI OF THE SG-1B (MOD. 50) RADAR.

Abstract

The bearing cursor and the antenna trace of the PPI on the SG-1b (Mod. 50) radar are often found to be non-coincident. This report summarizes the results of a study on the alignment of the cursor and of the antenna trace under various conditions. No change in alignment between the antenna trace and bearing cursor was observed after the equipment was in the 'on' position for a six hour period. Slight changes in alignment were observed after the equipment had been in 'stand-by' condition overnight. Larger changes in alignment were observed as a result of movement of the chassis in and out of the console. Computations from these data show the maximum bearing errors resulting from misalignment.
