US Air Force video shows how to use manual triangulation to track aircraft
Sometimes you see declassified video or data and wonder how it ever became classified in the first place – and sometimes you can sort of understand. The National Archives recently declassified an interesting video that details a way, using mostly hand-drawn images and a “dramatic soundtrack,” to explain one way the US Air Force used to get around electronic jamming technologies.
Such technologies ruin data reliability that our adversaries used with “frightening efficiency,” the video explains
In this case the video details a modification that could be made to a radar site that could let technicians or other intelligence analysts manually track incoming aircraft using a triangulation technique.
Clearly a cold war-era video, it details what was known as Operation MANTRAC (Manual Angle Tracking Capability) and “shows the method of using two or more radar stations that are being jammed, and the triangulation method used to obtain a track of incoming aircraft. It includes a demonstration of the technique using a MANTRAC plotting board.”
Interesting stuff.
