ABSTRACT:
A training cockpit on a hydraulic motion system is responsive to the cockpit controls to simulate an aircraft in flight. A simulated radar display of the aircraft vicinity is provided from a data base memory of the topographic and cultural data of the gaming area.
As the antenna scans, particular blocks of data are transferred from the district memory to smaller sector core memories at high speed access and transfer rates. The sector memory provides a line of data for each sweep of the simulated radar. Reflectance and elevational data is retrieved from the sector memories and processed, one sweep at a time, through digital radar equation computation equipment which calculates the brightness of each spot in the simulated radar display. This digital brightness data is processed through an earth curvature subsystem which modifies the brightness in accordance with the horizon effect. The modified brightness is applied to a digital to analog converter and then to the radar display. A central computer coordinates the data flow with the flight parameters-position, speed, altitude, direction, etc., of the simulated aircraft.
