Scene simulation and modeling of InfraRed search and track sensor for air-borne long range point targets

Complexities involved in the state-of-the-art Infrared Search and Track (IRST) systems require comprehensive model for scene simulation in which the interplay between sensor, target, background and atmosphere can be modelled and evaluated for scenarios as maximum as possible. In this paper, we discuss our simplified model of infrared (IR) scene generation which has been developed for long range, air-borne point targets. IRST systems operate in a wide Field-of-Regard (FOR) by continuously scanning the line-of-sight of the sensor. To cover the entire FOR scanning mechanism has been implemented in the module where different scanning speed in the azimuth and elevation directions can be defined. Further, we present our results for point target detection and tracking by implementing different standard algorithms on the generated scenarios using the developed software model.
