Synthesis of High-Resolution Radar Systems for Display Simulation and Training

摘要

A comprehensive analysis was conducted of the theory and practice of utilizing digital techniques for simulating high-resolution radar systems. The objective was to simulate radar displays of cultural complexes for navigation training. Three major phases of this effort are: (1) develop tractable scattering models, (2) construct a data base, and (3) define a simulation procedure that is computationally efficient. The techniques developed in this report are generally applicable for any radar or processor, whether of brute-force type or synthetic aperature. To validate the approach, a 30 city-block area is incorporated into a digital data base by using photogrammetric techniques on aerial photography. From this data base, a radar display is simulated that is in good agreement with actual radar imagery. The practicality of a real-time digital simulation is demonstrated. (Author)
