Evaluation methodology for the advanced seeker concepts

This report describes the methodology used to evaluate two multi-sensor seeker concepts for ground target application. One concept utilizes two-way communication with the "national network" and the other is autonomous after launch. The missiles are of UCAV-type, i.e. a carrier and several sub-munitions. The evaluation will be concentrated on classification, but detection and tracking during ECM will also be considered. The evaluation will mainly be carried out by simulations. High resolution CAD-models are used as target models, with IR-textures "draped" on the models, alternatively the IR signatures will be calculated using thermodynamic based tools. Radar signatures are calculate from the geometry in the CAD-models. With the measurement system "IRmm" it is possible to verify some of the simulations. The performance and usefulness for different seeker functions are described for the used sensors, IR and radar. The tracking, detection and classification performance are the main issues to be evaluated. To be able to get an "absolute" measurement of algorithm performance a methodology based on statistical theory will be tried. The ECM resistance will be evaluated together with another project. By giving the simulation environment the ability to simulate some ECM-methods, it will be possible to evaluate how classification is influenced, but also get some experience from other seeker functions.
