Simulation of the Influence of Atmospheric Parameters on Infrared Target Signature

摘要

The radiation temperature of targets is studied as a function of horizontal range for different target temperatures and atmospheric conditions. The atmospheric infrared window regions 3 to 5 and 8 to 14 micrometers are investigated simulating AGA 680 cameras as sensors. Atmospheric parameters are summer/winter atmospheres, rural/maritime aerosols, humidity, and meteorological range. Target/background contrast of radiation temperature is given as a function of the chosen atmospheric and range parameters. Target detection probabilities for simple homogeneous backgrounds can be calculated from the results.
