Paper Abstract

This paper describes the Illowra forward looking infrared (FLIR) performance model, which has been developed by the Defence Science and Technology Organisation (DSTO) and British Aerospace Australia (BAeA). The Illowra model enables calculations of system performance to be carried out for a wide range of FLIR technologies including thermal, photoconductive, and photovoltaic detector based systems used in various staring and scanning detector geometries. Illowra can produce images of target/background scenes, showing spatial and noise effects introduced by a FLIR system. The performance of the human observer, in terms of target detection, recognition, and identification probability, is calculated using the Oracle visual performance model developed by British Aerospace, UK. An outline of the structure and operation of the model is given, followed by a description of how Illowra has been used for various applications within DSTO. The paper concludes with a description of some of the most recent enhancements to Illowra.
