An Analysis of the Effects of Digitized Terrain Errors on Geometric Pairing

摘要

The One Tactical Engagement Simulation System (OneTESS) is the U.S. Army's vision for the next generation tactical engagement simulation system (TESS), capable of supporting Force-on-Force (FOF) and Force-on-Target (FOT) training and testing for all levels brigade and below at homestation, combat training centers (CTCs), and deployed sites. Current TESS has relied upon the Multiple Integrated Laser Engagement System (MILES) for a number of years, using a laser to pair the shooter to the potential target(s). OneTESS will use a pairing method called geometric pairing (geo-pairing), which uses a set of information about both the shooter and target, such as locations, weapon orientations, velocities, and weapon projectile velocities, to resolve an engagement. A previous paper [1] introduces various potential sources of error for a geo-pairing solution. This paper goes into greater depth regarding the impact of errors that originate within digitized terrain representations, beginning with a short introduction into the OneTESS. The next section will explain the characteristics of digital terrain expected to be used by OneTESS followed by a mathematical analysis of the impacts of that representation. A summary and conclusion containing recommendations will close this paper.
