The mission of an Infrared Search and Track (IRST) system is to detect and locate (sometimes called find and fix) enemy
aircraft at significant ranges. Two extreme opposite examples of IRST applications are 1) long range offensive aircraft
detection when electronic warfare equipment is jammed, compromised, or intentionally turned off, and 2) distributed
aperture systems where enemy aircraft may be in the proximity of the host aircraft. Past IRST systems have been
primarily long range offensive systems that were based on the LWIR second generation thermal imager. The new IRST
systems are primarily based on staring infrared focal planes and sensors.
In the same manner that FLIR92 did not work well in the design of staring infrared cameras (NVTherm was developed to
address staring infrared sensor performance), current modeling techniques do not adequately describe the performance of
a staring IRST sensor. There are no standard military IRST models (per AFRL and NAVAIR), and each program
appears to perform their own modeling. For this reason, L-3 has decided to develop a corporate model, working with
AFRL and NAVAIR, for the analysis, design, and evaluation of IRST concepts, programs, and solutions. This paper
provides some of the first analyses in the L-3 IRST model development program for the optimization of staring IRST
