Cove Point of the General Motors Radiant Heat Detector in Tracking Landing Craft
Abstract
Measurements of the flux of radiation from LCT and LCI landing craft as a function of range were made with the General Motors Radiant Heat Detector in clear we9ther to ranges of 4000 and 4500 yards on an LCT and 5800 yards on an LCI. The instrument detected and automatically tracked LCT targets at ranges of about 5000 yards, and the LCI at ranges in excess of 8000 yards. Temperature measurements on the surfaces of the ships and on the sky-sea background permitted computation of total net emission by the targets. Tracking ranges computed from these results, neglecting atmospheric absorption, led to a value of 5200 yards expected range on LCT comparable with an observed range of 5100 yards where tracking was strong.
