Abstract
Nowadays, Combat Systems have to counter different kinds of threats including surface targets and air targets. In that last case, fast-moving incoming missiles such as BUNT missiles turn out to be the most threatening ones. Indeed, their maneuver capabilities are difficult to be managed by tracking processes. Plus, when a defense missile launched by the fire system is remote conrolled, threat maneuvers may decrease the interception capabilities of the Combat System i.e. the Probability to Kill (PK). The article addresses this situation. A practical aglorithm of data fusion is presented; the case studied is a short-range fire control platform. The Combat System features a dual-sensor system that combines a Track Radar and a Thermal Imager while a Missile Guidance Unit (MGU) takes into account the incoming target and the Defense Missile tracks to remote control the missile towards its target. Then, statistic results of tracking performances and interception sequences are given for different incoming missile scenarios and sensors suites (radar-alone configuration, combination of the active sensor with a Thermal Imager). They highlight how data fusion reacts with the overall anti-missiles fire system performances and especially its miss distance.
