A STUDY OF FACTORS AFFECTING OPERATION OF THE VG REMOTE PPI

摘要

A study was undertaken at the Systems Research Field Laboratory to determine the effects of various electronic and optical factors on the operation of the VG. Among the factors studied are the video gain, the CRT bias, the limiting of PPI adapters, use of a higher accelerating voltage on the CRT, the type of viewing screen, and the intensity of the reflected light. An analysis of the operation of the VG was made in terms of detectibility (ability of the targets to be seen), vari¬ability of detectibility scores, and discrlmlnabillty (ability of targets to be distinguished from each other). Each of these factors was studied separately and in relation to the other factors
