The report describes technical and tactical need for EW in urbanized terrain. This pre study has a focus on the small front units. Studies and discussions in this report have been concentrated at systems that can be used directly of these front units. This pre study suggests (even if it is not within the task for the pre study) that the first thing to do is to make sure ever rifleman has his/hers own communication radio. The research areas of interest for EW in urban environment are: Location of communications in urbanized terrain by using Electronic Support Short range communication based on an miniaturized EW-system Protection against remote controlled IED ("Improvised Explosive Devices") EW-suite in urbanized terrain HPM - UWB HPM - Effects when used in urbanized terrain HPM - Effects on simple generic civilian objects Suggestions for activities in other research areas than EW are given in the report.
