The report presents a logical design of a natural terrain radar land mass simulator, techniques for incorporating radar effects, and cultural terrain into the simulator, and relationship between simulator design and specific operational requirements. The results of this work indicate that the techniques developed are feasible from an engineering standpoint but are impractical due to cost considerations. A firmer understanding of the information content of maps and digital representation techniques must be established to compress the data to a degree whereby an economically feasible device can be developed.

To generate input data with a 50-foot resolution and fifteen shades of gray for advanced high-resolution digital radar simulators, this research examined and defined data sources and processing techniques. Limited to the Continental United States and to unclassified information, the data sources included all known aerial mapping imagery and topographic maps. All existing image processing techniques and devices were examined to define their operating principles. This review led to the conclusion that adequate geometric information for radar simulation data could be extracted from the current data sources and that existing processing capabilities could be combined into a feasible automatic system. In related work, non-parametric three-dimensional resections were calculated on a digital computer, and mathematical concepts were developed to give a computer system the capability of interpreting the physical characteristics in photos by using cues as done by a trained photo interpreter.
