Effectiveness of side-looking radar in simulated orbit as a function of reference data support.

Abstract

Subjects' ability to identify ground targets through side-looking radar imagery from a simulated space orbit was evaluated. Two levels of target localization data (Precise versus General) were provided on a reference display either simultaneously with or immediately in advance of the presentation of targets on an adjacent TV monitor. Precise Target Localization Groups performed better both with respect to speed and accuracy of identification. Simultaneous and advanced presentation of reference data produced essentially equivalent accuracy results but subjects in the latter condition responded significantly faster. It was concluded that precise target localization, as may be provided by preflight intelligence or inflight information from forward looking sensors, is particularly important in supporting target identification by side-looking radar at near real time rates. Possible advantages of advanced presentation of localization cues were less clearly established.
