Flight Training Simulator: Surface Texturing via Pseudo Random Noise Codes.
Joseph F. deSpautz, Michael B Bender, Virginia M McNamara · Defense Technical Information Center (DTIC) · 1980
Increased use of infrared and low light level television systems within the operational environment has presented increasingly difficult problems to the technology of simulation systems in the area of target identification, textural cues, and simulation fidelity. The principal effort reported here has been to develop a software simulation using cyclic codes for providing surface texture without the use of typical computer image generation (CIG) edge-type algorithms. The latter type algorithms, when used to provide valid and realistic surface detail, cause the edge processing load to exceed system capability. Cyclic code techniques provide a compact texture data base definition that is versatile, has substantial total assignment capability, and is based on real-time simulation concepts. The simulator system was delivered and made operational on the Sigma 5 facility using the ACTES facility for offline video data storage, retrieval and display. The software is user interactive from a remote terminal and includes capabilities for modeling the data base, display characteristics, aircraft positioning, and simulator control of printouts and default options.
