Paper Abstract

Herein is described a method which objective is to enhance the speed at which terrain inter visibility calculations are performed for unknown or "pop-up" ground based radar threats. The problem with current inter visibility techniques is their inability to perform in real time, thereby jeopardizing the survivability and success of the mission. The main computational hurdle is the intensive checking of the radar extensions against the surrounding terrain. These very repetitive line-of-sight calculations result in a detailed mapping of volumes within which an object is non-detectable. We outline a set of high level methods which checks a selected set of lines for intersect with a subset of terrain elements.
