THE ROLE OF THE DDP-24 DIGITAL COMPUTER IN GENERATING TARGET AND IMPACT DATA FOR VIDEO PRESENTATION TO AN AIRCRAFT GUNNER IN A LARGE-SCALE AVIONICS SIMULATION FACILITY.

This paper describes a DDP-24 program used to interface between the state variables of an aircraft and a target-impact video generator. The video generator was designed in-house for use in the Tactical Avionics Systems Simulator Facility at the U. S. Army Electronics Command, Fort Monmouth, New Jersey. The generator provides a means of evaluating fire-power effectiveness of various airborne weapon systems. The DDP-24 receives aircraft state variables and ballistic data through analog to digital conversion in a hybrid computer system simulating the aircraft. The program transforms the received data, calculates the orientation and location of three video cameras, determines the size and position of the target area, as well as the location of the shell impacts, and then drives the appropriate video camera for side-window viewing. The target and impact data words are sent out to the video generator, which converts them into video signals superimposed on normal background terrain video signals. In this way the gunner in the simulator is provided with a visual representation of hit or miss via the closed-circuit television system. Author
