Abstract
The research on infrared signal attenuation caused by solid motor exhaust plume is very important to detection and guidance of infrared signal. The attenuation mechanism of IR signal was mainly introduced, and the effective method for calculating infrared signal attenuation was put forward, then DROP software was programmed. The ratio of spectrum transmission of water drop and solid particle cluster was calculated by means of the DROP software, and the results were compared with calculation data of SIRRM software. The results show that two kinds of data are consistent, which can provide reference to engineering application.
