Sirius is a long range infra red search and track system (LR- IRST) and intended to be used in an anti air warfare (AAW) multisensor suite on board of modern frigates. This Dutch/Canadian development program started 1/1/95 and includes also the evaluation of the system in warm and cold water scenarios. The operational requirements were drafted by both the national navies. The primary task is automatic detection, tracking and reporting of seaskimming missiles at long range. The design is based on recent experiences with IRSTs and the latest technological achievements in the areas of processing capabilities and IR-detectors. In this presentation design drivers and main technical choices are discussed.
