The development of a mathematical model of an aircraft- mounted infra-red search and track (IRST) system is reported. In addition to accurately simulating the detection, tracking and classification aspects of the IRST sensor, the model also encompasses the generation of artificial IR scenes with embedded targets, atmospheric effects, an aircraft and target dynamics model, an inertial navigation system error model and a simple weapons system simulation. External files containing modeled IR backgrounds or real recorded IR data can be accepted via a test harness as scenic input for a simulation run in order to analyze system performance during flight trials. This paper reviews the evolution of the mathematical model from IR system concepts and focuses on the techniques used to produce a performance model of a new IRST system. Design and performance aspects of a number of components within the model are described and the methodology used to achieve an accurate simulation which is both representative and efficient is also discussed.
