  • Patent number: 8576109
    Abstract: A method and a configuration are provided for generating high-energy microwave pulses, in particular based on HPEM technology. The objects include, on the one hand. increasing the energy density of pulses and, on the other hand, also making the relevant appliances more compact. For that purpose, a large-area configuration of a multiplicity of, preferably non-linear, semiconductor components is used in the area of the antenna, for pulse shaping.
    Type: Grant

  • Publication number: 20080174469
    Abstract: A method and a system for defense against surface-to-air missiles (Manpads), which represent a threat to military and civil aircraft during takeoff and landing. For missile defense, the missile is jammed by irradiating it with electromagnetic jamming radiation. This jamming radiation may be constituted of continuous-wave irradiation or frequency packets with a defined pulse repetition rate.

  • Patent number: 7375444
    Abstract: A microwave generator (11) has a parallel connection of series connections of uncontrolled discharge spark gaps (13) and charge storage means (12) which are charged up by way of charging resistors (17) and an inductor (19) common to all parallel connections, from a high voltage generator (26), until the respective spark gaps (13) short-circuit by way of arcs and the storage means (12) are discharged again by way of the inductor (19). The oscillating short-circuit currents which thus occur in stochastic steep-edged manner and which are superimposed on each other in the inductor (19) are emitted by way of an antenna (21) connected in single-pole manner thereto in the form of a high-energy microwave spectrum which is wide-band in accordance with the arc switching speed, with a spectral key point which is determined by the inductor (19).

  • Patent number: 6969944
    Abstract: A very compact interference frequency generator (11) which emits with an extremely wide band width and extremely powerfully is afforded by the combination of a mechanical pulse generator (25) with two piezoelectric pillars (13) which are disposed axially in succession and which can be axially acted upon by the pulse generator (25) and which are electrically connected in series in opposite relationship and which are electrically conductively connected with their mutually remote ends (18) to electrodes (34) which extend parallel to the piezoelectric pillars (13) to an electrically conductive coupling portion (15) between the piezoelectric pillars (13) where they end as electrodes (36) of an axial spark gap and at the same time spark gaps (37) which are oriented inclinedly radially towards the coupling portion (15).

  • Patent number: 6822394
    Abstract: For a compact microwave generator (11) with powerfully wide-band microwave radiation in which there is a marked resonance increase whose frequency center of gravity is variable in order to be able to adapt the power center in respect of the radiated wavelengths to the geometrical structure of a circuit configuration to be disturbed, a conductor (29) which coaxially surrounds the spark gap (13) between the electrodes (14-15) is electrically connected to one of the two electrodes (15) mechanically adjustably in its effective length as a variable resonator.
