An electronic counter measures solution. Jamming signals are emitted
towards a threat to improve chances of survival for at least two
vehicles, which are physically separated from one another, however
associated with one another in a group. Each of the at least two vehicles
receives a wireless time reference signal from an external resource. The
vehicles exchange messages over a wireless data link. The messages
pertain to usage of at least one electronic warfare resource in each
vehicle. Based on the messages and the time reference signal the usage of
at least one first electronic warfare resource in a first vehicle is
coordinated with the usage of at least one second electronic warfare
resource in a second vehicle, such that a particular type of jamming
signal is emitted alternately either from the at least one first resource
or from the at least one second resource, essentially without any
overlaps or gaps in time. Thereby, a false target is created between the
vehicles with respect to a weapon which operates in a so-called
Home-on-Jam mode.
