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.

Several methods have been devised for processing a digital radar data base to create simulated mapping-radar scope images. To aid in the evaluation of these various methods, NAVTRAEQUIPCEN has developed a system which operates in conjunction with its TRADEC System to produce a pseudo real-time radar display. Simulation methods can be simulated on this system for comparison and evaluation. The objective of this report is to describe the software, developed in-house, which processes raw digital radar data to produce a 'baseline' simulation against which other methods may be compared. The software is functionally broken down into three tasks: terrain data processing, cultural data processing, and radar effects. It is written in a high-level language, FORTRAN, to facilitate experimentation and modification. (Author).

The report summarizes work in simulating the Digital Radar Landmass Simulator (DRLMS) for evaluation purposes. The software produced under this contract is run on a computing facility to generate simulated radar images on a radar display. The work done consisted of two parts: production of a data base and simulation of the hardware's processing of this data base. In development of the data base, the contractor compressed government-supplied data, in a grid format, to an 'edges' representation. The edges are ridge and valley lines, in the case of terrain data, and reflectance boundaries for culture data. The algorithms used to achieve this representation are not to be construed as 'optimum'. They are, however, vehicles for studying a technique and can be easily modified by the user if desired.
