Abstract

The initial studies that have been conducted to derive a standard set of geometric symbols for application to future radar assisted air defense systems are presented. Experiment I was aimed at determining whether or not particular shapes exist in our population as stereotypes for the meanings friendly, hostile, and unknown. The second step in the research was directed towards finding a set of symbols which can be easily discriminated and quickly reacted to in a paper-and-pencil mode.
