AN EXAMPLE OF AN EARLY TECHNIQUE FOR VISIBILITY CALCULATIONS,

Abstract

This report describes results from previously unreported visibility calculations made in the spring of 1957, of aerial observer sighting and recognition ranges for a complex object. The object is a toy model scaled to vehicle size, lighted by sun and sky, and screened by the real atmosphere. Most of the ranges are presented graphically as a function of altitude for one search method; viz, visual fixation at the optimal angle of sight, area coverage being provided by the forward movement of the plane. Sample results are also given for other methods of search. (Author)
