Measuring the infrared signature of large civilian aircraft has
become increasingly important due to the proliferation of
man-portable air defense systems (MANPADS) and the increasing
threat of their use by terrorists. Because of the range of these
shoulder-fired weapons, most aircraft flying over 20,000 feet are
safe from the threat; however, aircraft taking-off or landing are
extremely vulnerable. A radiometric model was developed to simulate
a large commercial aircraft's infrared intensity during these two
critical phases of flight. The radiometric model was largely based
on the dimensions of a Boeing 747-400 aircraft. It is capable of
simulating elevation angles between -20 degrees and +20 degrees, as
well as 360 degrees in azimuth in its projected area analysis of
the faceted model. The model utilizes an obscuration matrix to
determine which parts of the aircraft are in view by the observer
and thus contribute to the aircraft's intensity. A simple
one-bounce reflection matrix was also included to incorporate
reflections of hot parts off other body parts as well as earth- and
sky-shine contributions to the overall intensity.
