High Target Visibility Analysis
J. J. Kim · Defense Technical Information Center (DTIC) · 1994
This paper presents an approach to visibility analysis for a target located high over a terrain made of discrete elevation points. This analysis is a special subset of a general terrain intervisibility analysis problem. It is an efficient algorithm based on a variation of the 'line-of sight' approach, being k-time faster than the ordinary approach, where k is the ratio of the highest terrain elevation to the target altitude.
