Patent ID: 7339515

Claim:
A method of producing jamming signals from a distributed counter measures system including at least two stations ( 100 , 200 , 300 ) which are physically separated from one another and associated with one another in a group of stations, each station ( 100 ) having a local set ( 140 ) of electronic warfare resources (R 11 , . . . , R 1i ) including at least one resource which is adapted to generate and emit at least one type of jamming signal (J A ), the method in each station ( 100 ) comprising exchanging messages (D) over a wireless data link (L), wherein the method comprising the steps of: exchanging the messages (D) with the at least one other station ( 200 , 300 ) in the group, the messages (D) sent from a particular station ( 100 ) comprising data pertaining to an availability status (D res-status ) for each resource in the station's ( 100 ) local set ( 140 ) and a threat status (D thr-status ) registered by the station ( 100 ); and checking whether the station ( 100 ) shall assume a central planning function in respect of a complete set of electronic warfare resources ( 140 + 240 + 340 ) including all electronic warfare resources (R 11 , . . . , R 1i ; R 21 , . . . , R 1j ; R n1 , . . . , R nk ) of the at lease two stations ( 100 , 200 , 300 ) in the group; and given that the station ( 100 ) is to assume the central planning function, the method comprising coordinating any emission of jamming signals (J A ; J B ) from the resources in the complete set based on: estimated geometric interrelationships between the at least two stations ( 100 , 200 , 300 ) in the group, estimated geometric relationships between the at least two stations ( 100 , 200 , 300 ) in the group and at least one threat (X 1 , X 2 ) registered by at least one station in the group, and the respective local set ( 140 , 240 , 340 ) of each station ( 100 , 200 , 300 ) in the group.
