Multi sensor seeker IR/mm-wave, final report

At FOI (FOA) we have been studying multisensor technique and datafusion for missile seekers since 1993. The reason for starting this research was the increasing international interest in the area and the problem with the high secrecy. It was and is still very difficult and sometimes impossible to get any information on international seekers and their abilities. The current project has been going on for 3 years and shows the possibilities for a seeker that uses IR- and mmwave sensors for ground target applications. We have developed and produced a measurement- and signal processing system consisting of the two sensors, a steerable platform and hard- and software for the signal processing. The system has been used for data collection in real-time and for validation and demonstration of seeker functions in near real-time. In the report the possibilities with autonomous detection and classification are described. A traditional missile seeker tracks one target with one sensor that is locked on the target. The tracker in our seeker tracks several targets at the same time with information from several independent sensors, which don´t need to be co-located. This concept allows you to apply target identification methods on every track and most simple decoys can be detected this way. Deception with i.e. flares and chaff is then more difficult to achieve, which in combination with multisensors for target tracking gives you a system that is very hard to deceive.
