Abstract

A method for calculation of the target range of an airborne IRST has been verified with data from flight trials. The calculation method includes modelling of sensor performance, atmospheric transmission and infrared radiation from target and background. The flight trials were performed with the IR-OTIS system mounted on a Saab JA37 Viggen fighter aircraft, and a similar aircraft serving as target. Detection range was measured at various flight altitudes, for front and rear aspect. The correspondence between measured and predicted range is very good, with a deviation of less than 10 %.
