Abstract

A raster-type CRT display has been investigated as a means of improving the visual detection of weak radar signals. Two raster displays of different sizes were compared with a single-trace display under two conditions of screen brightness and signal-noise levels. The smaller of the two rasters was found to give significantly lower detection thresholds; its greatest superiority is shown, however, at the lower signal-noise and brightness levels.
