EFFECTS OF TELEVISION BANDWIDTH ON TARGET IDENTIFICATION,

Abstract

A laboratory test program was conducted to evaluate the effects of video signal bandwidth and target contrast ratio on visual target identification. The results of the tests indicate that: (1) reducing the target contrast ratio degrades target identification abilities; (2) reducing the video signal bandwidth degrades target identification abilities; (3) the ability to identify targets is degraded less by video bandwidth reductions for low contrast targets than it is degraded by high contrast targets; (4) the ability to identify targets is degraded less by target contrast ratio reductions when using a narrow video bandwidth rather than using a wide video bandwidth.
