Title:RADAR PART 11 : the PPI and skiatron - an introduction [Main Title]
Film Number:ADM 2560
Other titles:
Summary: Eleventh in series discusses the PPI and the Skiatron.
Description: The PPI scan revolves at the same bearing and speed as the aerial, and the echoes picked up and shown on the display screen represent a comprehensive plan of the surrounding area (it is a recognisably modern radar set compared to the previous 'A-scan' equipment). The film describes the applications and proper use of the instrument, and shows the distribution of PPI display screens in a King George V Class battleship and a aircraft carrier. The Skiatron, used in aircraft carriers for plotting the courses of surrounding planes, is an adaptation of the PPI with a different display system, and is shown only briefly. "Having seen this film, you will appreciate that if radar can be said to be capable of playing a valuable part in gunnery, AS warfare, fighter direction and navigation, the invention of the PPI and the Skiatron extends its usefulness and increases its value immeasurably."
