Definitions

  • the present invention relates to a method for generating microwave pulses of high energy according to the preamble of claim 1. Furthermore, the present invention relates to an arrangement for generating microwave pulses of high energy according to the preamble of claim 7.
  • Microwave pulses high energy or high energy density are nowadays used to electronic components threatening objects, such as those of time-triggered or mobile phone-controlled explosives such.
  • B. booby traps or the like To destroy or at least dysfunctional.
  • Corresponding microwave pulse generating systems are preferably used in the form of portable systems or carried on vehicles. They should therefore be as compact as possible. The possibility of using such systems is not limited to the near field, but can be extended to larger ranges, for example, with the aim of impairing the trajectory of electronically controlled objects such. B. missiles or the like. One strives for the applications described to produce pulses with the highest possible energy density and power.
  • a microwave pulse generator in which a pulse with a rise in the order of a nanosecond and an amplitude in the range of 12-20 kV is generated at a first spark gap.
  • This pulse is then converted into a damped sine wave (DS pulse) via another series-connected spark gap, which acts as a switch, and emitted via a reflector or an antenna.
  • DS pulse damped sine wave
  • the slope of the radiated pulse is usually limited.
  • the object of the present invention is to provide a generic method as well as a generic arrangement which, on the one hand, enables a high energy density of the microwave pulse to be radiated, a simple construction and a reduction in dimension compared with previous arrangements and, on the other hand allows increased flexibility in the field of pulse shaping.
  • the idea of the present invention is to provide in the area of the antenna a large-area, array-like arrangement consisting of a multiplicity of surface-distributed, preferably parallel and / or serially connected, conductor components.
  • the pulse originating from the pulse generator generates or induces in the planar arrangement of the conductor components a surface current which in turn generates the field to be radiated.
  • the idea offers the advantage of being able to undertake targeted measures concerning the shaping of the pulse to be radiated by means of the conductor components. For example, by using nonlinear conductor components, ie, conductor components having a non-linear characteristic, an effective increase in the edge steepness of the resultant pulse generated by the large-area arrangement can be achieved. Such a pulse has a very high energy density.
  • each conductor component is inversely proportional to the total number of conductor components by the incoming impulse loaded less. This in turn results in the advantage of using conductor components, in particular semiconductor components, as conductor components which would, in themselves, be exposed to physical limitations and therefore could not be used.
  • the cascading can be serial, parallel or preferably parallel and serial.
  • the energy flow resulting from the incoming impulse is optimally distributed in the latter case.
  • the non-linearity that is, the presence of a non-linear characteristic can be a property of the individual conductor components.
  • the cascade of the conductor components may also have a total of nonlinearity.
  • the invention makes it possible, in addition to passive d. H. non-controllable also to use active conductor elements. If the conductor components are active components, targeted activation and thus targeted shaping of the pulse can take place in the region of the antenna. In particular, additional patterns can be modeled on the pulse. A modulation of the pulse can be an important additional criterion, especially in the control of directional pulses (beam steering).
  • the active influencing can be carried out in particular by applying a voltage to the conductor components or by changing the applied voltage or the current intensity.
  • a reflector antenna z As regards the arrangement also claimed in the side-by-side order for the generation of microwave pulses of high energy, the use of a reflector antenna z.
  • IRA antenna impulse radiating antenna
  • the conductor components can be mounted well on the large-area reflector of the antenna.
  • the invention is not limited thereto.
  • a so-called horn antenna is also suitable, since the planar arrangement of the conductor components can in this case be located on the wall which closes the widening horn. This is irradiated by the pulse at the exit.
  • Other planar antennas can also be used.
  • Semiconductor components such as diodes, are particularly suitable for implementing nonlinear conductor components.
  • a diode makes it possible to increase the edge steepness of the outgoing pulse in comparison to the pulse entering the diode.
  • a diode can be used as a conductor component and an inductance, especially a non-linear inductance.
  • the patch panels are insulated from each other.
  • the patch fields can also be separated from each other, eg. B. resistive or inductive, decoupled or interconnected. This allows increased flexibility in the field of pulse shaping and design of the reflector.
  • Fig. 3 shows a greatly simplified arrangement for generating a microwave pulse of high energy, z. B. a DS (damped sinusoid) pulse.
  • the arrangement comprises a power source 1, z. B. a battery with a very high voltage.
  • the power source 1 feeds the pulse generator 2, for example, a so-called Marx generator, which generates a voltage pulse of the size unit of z. B. 0.3 to 3.0 MV and according to the form Fig. 1 generated.
  • the pulse generator 2 for example, a so-called Marx generator, which generates a voltage pulse of the size unit of z. B. 0.3 to 3.0 MV and according to the form Fig. 1 generated.
  • the pulse shaping unit 3 the aforementioned pulse is converted into a damped sine wave (DS), as in Fig. 2 is shown.
  • the DS pulse Via the antenna 4, the DS pulse is subsequently emitted to the environment.
  • a large-area arrangement 6, 15 of conductor components 5, in particular semiconductor components is provided.
  • the conductor components 5 are cascaded both in parallel and serially.
  • the arrangement 6, 15 is directly exposed to the electric and magnetic field of the pulse of the pulse generator 2 and the DS pulse of the pulse shaping unit 3.
  • the field of the incoming pulse generates a surface current, which in turn generates the field of the resulting pulse to be radiated.
  • An increase in the edge steepness of the pulse to be radiated with respect to the incoming pulse is achieved by a non-linear characteristic.
  • conductor elements 5 are used with non-linear characteristic.
  • FIGS. 6A and 6B it can be seen a plurality of individual mutually insulated patch panels 9 are provided on a reflector support 12.
  • the individual patch fields 9 are connected to one another in the direction of cascading via the nonlinear conductor components, in particular the diodes 7 or inductors 8.
  • the patch fields can also be separated from each other, eg. B. resistive or inductive, decoupled or interconnected. This allows increased flexibility in the field of pulse shaping and design of the reflector.
  • the planar arrangement 6 is expediently located in the region of the reflector 14 of an IRA antenna as shown in FIG Fig. 4 is shown.
  • the planar arrangement 6 of the individually distributed conductor elements 5 causes a total of a nonlinear reflection characteristic, which leads to an effective increase in the edge steepness of the radiated from the reflector 14 pulse and thus to a higher energy density.
  • the planar arrangement 15 may also be part of a wall 13 of a horn antenna, as in Fig. 5A is shown.
  • the pulse is formed while it passes through the wall 13 including the planar array 15 thereon of non-linear conductor elements 5.
  • the planar arrangement 15 of non-linear conductor elements 5 is in the embodiment according to Fig. 5A arranged in a plane perpendicular to the longitudinal axis.
  • the orientation can also be provided differently, for example obliquely to the longitudinal axis o. The like.
  • Fig. 5B it is shown for. B. possible to provide a planar arrangement of conductor elements, which comprises mutually arranged at an angle partial surfaces. Accordingly, one part of the conductor elements 5 runs along the wall 13 of the other part along the diverging part of the antenna.
  • the active control and control of the pulse characteristic to activate the printed circuit elements 5 as a whole or even only partially in order to influence the formation of the pulse in a targeted manner.
  • the conductor components may be passive but also active conductor components.
  • a control device 10 as in FIG Fig. 6B indicated
  • a suitable voltage or a current additional influence on the shape of the pulse to be radiated be taken.
  • a modulation of the pulse can be made, which in the so-called beam steering can be beneficial.
  • the present invention enables the generation of pulses of increased energy density without sacrificing the compactness of the devices concerned.
  • the invention enables active control and control of the pulse characteristic by the reflector.
  • the present invention therefore represents a very special contribution in the relevant field of technology.
