Patent number: 7868273Abstract: In order to make it possible to direct sufficient microwave energy at a target with an electronic device which is to be interfered with or to be destroyed, the beams (7) from at least two antenna arrays (10) are focused on an effective area (8) in the vicinity of that target, preferably from a vehicle (3) which is equipped with these arrays (10). For effective super-imposition of the emitted microwave energy (7) in the emission direction of in each case one of the arrays (10), the use of an arc for discharging the capacitance (43) of the resonator via its spark gap (13) is observed, and is recorded quasi-continuously optoelectronically. The electrode separation of the spark gap (13) or the fluid pressure of the dielectric in the vicinity of the spark gap (13) is then varied by control elements such that all of the spark gaps (13) in an array (10) ignite virtually at the same time, so that their discharge current pulses which lead to the emission of the microwave energy (7) start virtually in phase.Type: GrantFiled: October 17, 2006Date of Patent: January 11, 2011Assignee: Diehl BGT Defence GmbH & Co.Inventors: Andreas Ganghofer, Jürgen Urban, Geoffrey Staines

Patent number: 7842907Abstract: A microwave generator (10) having a hollow central electrode (12) with a front face including hollow emmission element (18), and having an outer electrode (14), which coaxially surrounds the central electrode (12) along an axially extending resonator section (16). The two electrodes (12, 14) define a spark gap (36) and are connected to a high-voltage source (38). An ultracompact microwave generator (10) is implemented by the high-voltage source (38) being arranged in the hollow central electrode (12) of the microwave generator (10) rather than on the outside thereof.Type: GrantFiled: June 29, 2007Date of Patent: November 30, 2010Assignee: Diehl BGT Defence GmbH Co., KGInventors: Robert Stark, Jürgen Urban
