Assessment of two multisensor missile seeker UCAV concepts

This report describes how two multisensor seeker UCAV concepts for ground target combat have been evaluated by simulation in synthetic environments, and the results of the assessement. The multisensor system uses radar and IR sensors. The scenarios used are taken from The Swedish Armed Forces "Framtida markmålsbekämpning" (Future ground target combat) and some typical situations are identified from that document. These have been used in the simulations, because it takes too long time to calculate a whole scenario. The radar simulations are made with "SPECRAY EM" and the IR-simulations with SceneServer for detection and with CameoSim and RadTherm for classification. High resolution CAD-models have been used as target models, both for radar and IR. The result of the detection performance with radar (SAR) and IR is very promising. All results for radar and IR are however based on simulated data. Classification with datafusion shows much smoother performance for all distances than either IR or radar each. With adequate signal processing we can achieve very good classification results from approximately 4.5 km distance. To get a reasonable confidence in the detection and classification results we need better signature base data and measurements to verify the result.
