A Land-Mass Radar Simulator Incorporating Ground and Contour Mapping and Terrain Avoidance Modes

This paper describes a method of simulating the radar displays of an airborne radar system. The simulator employs a scan-programmed vidicon tube and a low-power light source in conjunction with a three-dimensional terrain model to simulate radar return from land-mass formations, cultural areas, and target complexes. All effects of a moving aircraft, including velocity, heading, altitude, position, and attitude, are included in the simulation. This device will produce the displays for ground mapping, contour mapping and terrain clearance radar systems. It may be employed with an operational flight simulator or as a self-contained radar mission trainer for radar navigation and blind bombing operations.
