Abstract:

Targets on passive broadband sonar displays may be detected on the basis of three distinct stimulus attributes--target contrast, target marking density, and by grouping of similar brightnesses. Previous research has failed to isolate and systematically manipulate these variables. Methods of doing so are proposed in order to determine which of these stimulus attributes underlie target detection. Enhancing the proper variables should improve target detection. Keywords Marking density Contrast ratio Grouping similar brightnesses.
