Abstract
The invention relates to a distributed electronic counter measures solution, wherein jamming signals (JA; JB) may be emitted towards threats (X1, X2) from counter measures stations in multiple vehicles (A, B), which are physically separated from one another in order to improve the chances of survival the vehicles (A, B) as well as any other vehicles that are associated with these vehicles (A, B) in a group of vehicles. The vehicles in the group exchange messages (D) over a wireless data link (L), where the messages (D) sent from a particular station specify an availability status (Dres-status) for each electronic warfare resource in the station and a threat status (Dthr-status) registered by the station. A station in the group having a central planning function coordinates any jamming signals (JA; JB) emitted from the electronic warfare resources of the stations in the group, such that the resources are optimally used with respect to all of any registered threats (X1, X2). This coordination is based on estimated geometric interrelationships between the at least two stations in the group; estimated geometric relationships between the at least two stations in the group and at least one registered threat (X1, X2); and the respective resources of each station in the group.
