Abstract

An HPEM module (1,10) is provided, wherein the output pulse or the trigger pulse is transmitted on a single input trigger pulse (Trigger 2, 11) with an intermediate TTD network (5, 14) in a phase-defined and time-defined manner independent of frequency depending on the selected input of the electromagnetic lens via the geometric form of the lens. The trigger signal defines the time point for the generation of an UWB pulse in the pulse generator (3, 16). The main lobe of an antenna array (1*n) of several antennae (7, 15) is thus altered in the same number of positions in a plane accordingly as the number of adjustable phase differences or time differences. For an m*n array the alignment of the antenna lobe is no longer restricted to the plane.
