Abstract

Many U.S. Navy programs need to make predictions of ship-based thermal imaging sensor (TIS) and infrared search and track (IRST) performance against various threats. An important factor in calculating performance ranges is the atmospheric transmission. The energy from the target must first pass through the atmosphere before reaching the sensor and will be attenuated. The amount of attenuation depends on the sensor band and weather conditions and may have a considerable effect on the strength of the original signal. This paper describes a TIS modeling technique which allows simple, band-averaged estimates of atmospheric transmission to be made at any range and an IRST performance analysis tool, both of which make use of the NSWCDD weather databases for prediction of atmospheric transmission.
