This milestone report from the MOMS project covers the activities during 2006. The principal objective for the activities this year was to collect information and gain knowledge about phenomenology; i.e. features or characteristics that can give a detectable signature or contrast between object and background. Furthermore, sensor technologies have been considered, although this will be a main objective for the work in 2007. Laboratory experiments and small-scale field trials have been conducted. Results and activities in the work packages are presented. In particular, large efforts have been put into describing the threat objects and the scene variables. Furthermore, a phenomenology assessment was carried out to give an indication on how to focus the future work. Three classes of characteristics seemed to be superior: the spectral and spatial properties, respectively, and thermal inertia (temporal features). In addition, extensive experimental data collection activities have been done, including a long term out-door campaign covering all seasons.
