Report on A Summary of Measurements on Infrared Decoys for Homing Missiles, October, 1942 to March 1944

Abstract

This report summarizes recent measurements of the radiant intensity of heat sources of interest as decoys for infra-red-guided missiles, and in particular, the results of measurements of the apparent black body temperatures of gasoline-benzene filled incendiary bombs are discussed. The flames produced by these bombs containing 40 pound charges when ignited on water radiated in the 7.5 to 10 micron infra-red spectrum like 800 degrees K to 900 degrees K black bodies. The emission of heat was computed to be about 300 watts/ft2 in the 8.5 - 13 region, and each bomb was estimated to cover about 100 square feet emitting a total of JO KW in this spectral band. These numbers are a little larger than the results of earlier measurements on similar bombs containing 7 pound charges and radiating 180 watts/ft2 between 7.5 and 10 and about 3 KW over about 16 square feet total area.
