Video Mapping for the Data Relay Navigation System
Abstract
The data relay navigation system makes use of combined radar and map video information, both obtained at the ground installation and sent by radar link to all equipped aircraft. Video mapping is the technique of scanning a map by a cathode-ray indicator (flying-spot scanning) and then, by means of a phototube, converting the light impulses to video signals. Many of the refinements required for best resolution of map data are discussed. The best general type of video amplifier at the output of the phototube is indicated. The most adequate type of maps for pilot navigational purposes are also dealt with. A typical mixing circuit is given incorporating a level control, so that the pad data will not obscure radar targets.
