Description

Die Erfindung betrifft ein Verfahren sowie ein System zur Abwehr von Flugkörpern, welche Explosivstoffe mit piezoelektrischem Zünder aufweisen.The invention relates to a method and a system for defense against missiles which have explosives with a piezoelectric igniter.

Piezoelektrische Sensoren werden häufig als Einschlagszünder zur Auslösung explosiver Nutzlasten in ungelenkten Flugkörpern, z.B. Raketen oder Geschossen, verwendet. Ein typisches Beispiel eines solchen Flugkörpers ist die russische RPG-7 Panzerabwehrgranate, die in Fig. 1 dargestellt ist.Piezoelectric sensors are often used as impact fuses for triggering explosive payloads in unguided missiles, eg rockets or projectiles. A typical example of such a missile is the Russian RPG-7 antitank grenade, which in Fig. 1 is shown.

Diese Waffen sind weit verbreitet. Mit ihnen ist eine große Zahl von Opfern in den heutigen asymmetrischen Kriegsszenarien verbunden. Die wesentliche Verteidigung gegen derartige Waffen besteht in einer Panzerung. Diese ist jedoch nicht immer wirksam gegen den starken Plasmastrahl, der durch die Hohlladung erzeugt wird.These weapons are widely used. They are associated with a large number of victims in today's asymmetric war scenarios. The main defense against such weapons is armoring. However, this is not always effective against the strong plasma jet generated by the shaped charge.

Aktive Abwehrsysteme, mit denen versucht wird, den Flugkörper im Flug abzuschießen, wurden bereits vorgeschlagen. Diese sind aber sehr teuer, haben nur eine geringe Treffwahrscheinlichkeit und können bei Start des Flugkörpers im Nahbereich des Ziels nicht eingesetzt werden. Abwehrsysteme auf der Basis von Mikrowellenenergie sind nicht geeignet, da das Raketengehäuse eine Abschirmung gegenüber elektromagnetischer Strahlung bildet, die nur durch extreme Leistungspegel überwunden werden könnte.Active defense systems attempting to launch the missile in flight have already been proposed. However, these are very expensive, have a low chance of being hit and can not be used at the start of the missile in the vicinity of the target. Microwave energy based defense systems are not suitable because the rocket housing forms a shield against electromagnetic radiation that could only be overcome by extreme power levels.

Bekannt sind Fernzündanlagen gemäß DE 2250 630 B2 , mit denen unter Wasser angeordnete Sprengladungen durch Ultraschallsignale zur Detonation gebracht werden. Einer Sprengladung ist dabei ein Ultraschallempfänger zugeordnet, mit der das Ultraschallsignal empfangen und nach Wandlung in ein elektrisches Signal elektronisch weiter aufbereitet wird. Das Ausgangssignal des Ultraschallempfängers wird einem elektrischen Zünder zur Auslösung der Detonation zugeführt.Remote ignition systems are known according to DE 2250 630 B2 with which under explosive charges are brought by ultrasound signals to detonation. An explosive charge is assigned an ultrasonic receiver, with the the ultrasonic signal is received and processed electronically after conversion into an electrical signal. The output signal of the ultrasonic receiver is fed to an electric detonator for triggering the detonation.

Die DE 101 55 151 A1 beschreibt ein Verfahren und ein System gemäss den Oberbegriffen der Ansprüche 1 und 10.The DE 101 55 151 A1 describes a method and a system according to the preambles of claims 1 and 10.

Es ist Aufgabe der Erfindung, ein Verfahren sowie ein System anzugeben, das eine Abwehr von Flugkörpern mit hoher Zuverlässigkeit ermöglicht.It is an object of the invention to provide a method and a system that enables defense against missiles with high reliability.

Diese Aufgabe wird mit dem Verfahren nach Anspruch 1 sowie einem System nach Anspruch 10 gelöst. Vorteilhafte Ausführungen der Erfindung sind Gegenstand von Unteransprüchen.This object is achieved by the method according to claim 1 and a system according to claim 10. Advantageous embodiments of the invention are the subject of dependent claims.

Gemäß dem erfindungsgemäßen Verfahren wird zur Abwehr des anfliegenden Flugkörpers Ultraschallstrahlung ausgesandt, die den piezoelektrischen Zünder des anfliegenden Flugkörpers zu Schwingungen anregt und dadurch den Zünder, der nach dem Start des Flugkörpers aktiviert wurde, auslöst. Die Auslösung der explosiven Nutzlast erfolgt somit im Anflug des Flugkörpers weitab vom Ziel.According to the method of the invention, ultrasonic radiation is emitted to repel the approaching missile, which excites the piezoelectric detonator of the approaching missile to vibrations and thereby triggers the detonator, which was activated after the launch of the missile. The triggering of the explosive payload thus takes place in the approach of the missile far away from the target.

Die ausgesandte Ultraschallstrahlung kann das Metallgehäuse des Flugkörpers mit nur geringer Abschwächung durchdringen.The emitted ultrasonic radiation can penetrate the metal housing of the missile with only slight attenuation.

Die Ultraschallstrahlung kann gerichtet oder ungerichtet ausgestrahlt werden.The ultrasound radiation can be emitted directionally or non-directionally.

Die gerichtete Abstrahlung von Ultraschallenergie erfolgt bevorzugt in Form eines hochenergetischen Strahls mit geringem Öffnungswinkel.The directed emission of ultrasonic energy preferably takes place in the form of a high-energy beam with a small opening angle.

Bei einer gerichteten Abstrahlung wird bevorzugt ein Array von mehreren Ultraschallwandlern verwendet. Damit kann eine Ausrichtung der abgestrahlten Energie durch gezielte Phasensteuerung der Signale der einzelnen Ultraschallwandler erfolgen (Phased-Array-Technik). Die Ausrichtung erfolgt somit rein elektronisch ohne bewegte mechanische Bauteile.In a directional radiation, an array of a plurality of ultrasonic transducers is preferably used. Thus, an alignment of the radiated energy by targeted phase control of the signals of the individual ultrasonic transducers can be done (phased array technique). The alignment is thus purely electronic without moving mechanical components.

Alternativ kann jedoch auch eine mechanische Steuerung der Ausrichtung erfolgen, wie sie insbesondere bei Radarsystemen eingesetzt werden. Dazu wird der Ultraschallgenerator z.B. auf einem in Azimut und Elevation verstellbaren Drehtisch angeordnet.Alternatively, however, a mechanical control of the alignment can take place, as they are used in particular in radar systems. For this purpose, the ultrasonic generator eg arranged on a turntable adjustable in azimuth and elevation.

Darüber hinaus ist aber auch eine Kombination von elektronischer und mechanischer Ausrichtung möglich, derart, dass z.B. die Ausrichtung in Azimut mittels Drehtisch erfolgt, während die Ausrichtung in Elevation elektronisch mittels eines Arrays (oder im einfachsten Falle mittels einer Zeile) von Ultraschallgeneratoren erfolgt.In addition, however, a combination of electronic and mechanical alignment is possible, such that e.g. the alignment in azimuth by means of turntable, while the alignment in elevation is done electronically by means of an array (or in the simplest case by means of a line) of ultrasonic generators.

Bevorzugt wird die Frequenz der Ultraschallstrahlung derart gewählt, dass der piezoelektrische Zünder des anfliegenden Flugkörpers mit seiner natürlichen Resonanzfrequenz oder einer Harmonischen oder Sub-Harmonischen davon angeregt wird.Preferably, the frequency of the ultrasonic radiation is chosen such that the piezoelectric igniter of the approaching missile is excited with its natural resonant frequency or a harmonic or subharmonic thereof.

Um Toleranzen in der bekannten Resonanzfrequenz des Zünders oder Unsicherheiten hinsichtlich des genauen Werts der Resonanzfrequenz des Zünders zu kompensieren, kann die abgestrahlte Ultraschallfrequenz über einen gewissen Frequenzbereich variiert werden, z.B. durch lineare Frequenzmodulation.To compensate for tolerances in the known resonant frequency of the igniter or uncertainties as to the exact value of the resonant frequency of the igniter, the radiated ultrasound frequency can be varied over a certain frequency range, e.g. by linear frequency modulation.

Darüber hinaus wird bei der Wahl der abgestrahlten Ultraschallfrequenz vorteilhaft auch die Dopplerverschiebung berücksichtigt, die infolge der Relativgeschwindigkeit zwischen Flugkörper und der die Ultraschallstrahlung aussendenden Plattform entsteht. Auch in diesem Zusammenhang kann die Frequenz der Ultraschallstrahlung variiert werden, um Unsicherheiten hinsichtlich des genauen Werts der Dopplerfrequenz zu kompensieren.In addition, when choosing the radiated ultrasonic frequency, the Doppler shift, which arises as a result of the relative speed between the missile and the platform emitting the ultrasound radiation, is also advantageously taken into account. Also in this context, the frequency of the ultrasonic radiation can be varied to compensate for uncertainties in the exact value of the Doppler frequency.

Mit dem erfindungsgemäßen Verfahren wird eine zuverlässige und kostengünstige Abwehr von Flugkörpern realisiert. Direkte Treffer durch den Flugkörper und damit Bildung des zerstörerischen Plasma-Jets in unmittelbarer Nähe des Ziels können vermieden werden.With the method according to the invention a reliable and cost-effective defense of missiles is realized. Direct hits by the missile and thus formation of the destructive plasma jet in the immediate vicinity of the target can be avoided.

Das erfindungsgemäße Verfahren ist zur Abwehr sämtlicher gelenkter und ungelenkter Flugkörper, z.B. Raketen oder Geschossen, geeignet.The method according to the invention is suitable for the defense of all guided and unguided missiles, eg rockets or projectiles.

Ein System zur Durchführung des erfindungsgemäßen Verfahrens umfasst die folgenden Hauptkomponenten:

  1. (a) einen Flugkörperwarnsensor zur Detektion des Starts des feindlichen Flugkörpers.
    Hierzu können die an sich bekannten Flugkörperwarnsensoren auf der Basis von IR-, UV- oder Radarsensoren verwendet werden. Die Software des Warnsensors wird vorteilhaft auf die spezifische Signatur des relevanten Flugkörpers abgestimmt.
  2. (b) einen Trackingsensor zur Verfolgung des anfliegender Flugkörpers. Dies kann der selbe Sensor sein wie der Flugkörperwarnsensor oder aber ein zusätzlicher Sensor. Eingesetzt werden kann z.B. ein passiver elektrooptischer Sensor auf der Basis eines UV-Sensors. Aufgrund der begrenzten Brenndauer des Flugkörpers kommt jedoch bevorzugt ein IR-Sensor zur Anwendung. Ganz besonders geeignet ist ein aktiver Radarsensor, da das erfindungsgemäße Verfahren am effektivsten auf der Basis von Entfernungsinformationen durchgeführt werden kann.
  3. (c) eine Positioniereinrichtung zur Ausrichtung des Ultraschallstrahls auf den anfliegenden Flugkörper. Die Ausrichtung erfolgt derart, dass die Laufzeit des Ultraschallstrahls bis zum Ziel berücksichtigt wird.
    Hierzu kann z.B. ein rotierender Drehtisch eingesetzt werden, mit dem die Abstrahlung in Azimut und Elevation mechanisch eingestellt werden kann. Die Ausrichtung kann aber auch auf rein elektronischem Weg erfolgen, in dem die Phasen der einzelnen Ultraschallgeneratoren eines zweidimensionalen Arrays gezielt angesteuert werden. Hierfür können elektronisch angesteuerte akustische Arrays verwendet werden, wie sie z.B. aus Sonarsystemen für Unterwasseranwendungen bekannt sind.
  4. (d) eine Vorrichtung zur Erzeugung von Ultraschallwellen.
    Hierzu werden bevorzugt solche Vorrichtungen eingesetzt, die zur Erzeugung eines hoch-energetischen, stark gebündelten Ultraschallstrahls hoher Energiedichte geeignet sind. Insbesondere werden dazu zwei-dimensionale Arrays aus akustischen Einzelstrahlern verwendet. Deren Frequenz wird z.B. auf die Resonanzfrequenz des piezo-elektrischen Zünders der RPG7-Panzerabwehrgranate eingestellt. Die Ausrichtung der abgestrahlten Ultraschallenergie in Azimut und Elevation erfolgt - wie bereits oben unter (c) erläutert - elektronisch oder mechanisch oder aus einer Kombination von elektronischen und mechanischen Maßnahmen.
A system for carrying out the process according to the invention comprises the following main components:
  1. (a) a missile warning sensor for detecting the launch of the enemy missile.
    For this purpose, the known per se missile warning sensors can be used on the basis of IR, UV or radar sensors. The software of the warning sensor is advantageously matched to the specific signature of the relevant missile.
  2. (b) a tracking sensor for tracking the approaching missile. This may be the same sensor as the missile warning sensor or an additional sensor. For example, a passive electro-optical sensor based on a UV sensor can be used. Due to the limited burning time of the missile, however, an IR sensor is preferably used. An active radar sensor is very particularly suitable since the method according to the invention can be carried out most effectively on the basis of distance information.
  3. (C) a positioning device for aligning the ultrasonic beam to the approaching missile. The alignment is done in such a way that the transit time of the ultrasound beam up to the target is taken into account.
    For this example, a rotating turntable can be used with which the radiation in azimuth and elevation can be adjusted mechanically. However, the alignment can also take place in a purely electronic way, in which the phases of the individual ultrasonic generators of a two-dimensional array are specifically controlled. For this electronically controlled acoustic arrays can be used, as they are known for example from sonar systems for underwater applications.
  4. (d) a device for generating ultrasonic waves.
    For this purpose, such devices are preferably used, the high for generating a high-energy, highly concentrated ultrasonic beam Energy density are suitable. In particular, two-dimensional arrays of individual acoustic radiators are used for this purpose. Their frequency is set, for example, to the resonance frequency of the piezoelectric detonator of the RPG7 anti-tank grenade. The alignment of the radiated ultrasonic energy in azimuth and elevation takes place - as already explained above under (c) - electronically or mechanically or from a combination of electronic and mechanical measures.

Das beschriebene System kann sowohl von Luftfahrzeugen als auch von Landfahrzeugen getragen werden. Auch stationäre Anwendungen am Boden sind möglich. Ein besonderer Vorteil des erfindungsgemäßen Systems ist seine sehr geringe Reaktionszeit, was insbesondere bei Beschuss aus dem Nahbereich von wesentlicher Bedeutung ist.The described system can be carried by both aircraft and land vehicles. Stationary applications on the ground are also possible. A particular advantage of the system according to the invention is its very short reaction time, which is particularly important in the case of close-range bombardment.

Ein System S zur Durchführung des erfindungsgemäßen Verfahrens ist in schematischer Weise in Fig. 2 dargestellt. Es umfasst auf zwei gegenüberliegenden parallelen Seitenflächen jeweils ein Array 2 aus mehreren Ultraschallwandlern. Mit dieser Vorrichtung ist somit Schutz gegen anfliegende Flugkörper in großen Teilen der linken und rechten Hemisphäre möglich. Wenn notwendig, können weitere Wandler hinzugefügt werden, um volle Abdeckung über 360° zu erzielen. Die beiden Ultraschallarrays 2 sind starr an der Oberfläche des Systems S angebracht. Eine Ausrichtung der Ultraschallstrahlung 1 auf den anfliegenden Flugkörper 7.2 erfolgt in der gezeigten Ausführung rein elektronisch über eine entsprechende Phasensteuerung der einzelnen Ultraschallwandler eines Arrays 2. Eine zusätzliche, z.B. mechanische Positioniereinrichtung ist in diesem Fall nicht notwendig.A system S for carrying out the method according to the invention is shown schematically in FIG Fig. 2 shown. It comprises on two opposite parallel side surfaces in each case an array 2 of a plurality of ultrasonic transducers. With this device thus protection against approaching missiles in large parts of the left and right hemisphere is possible. If necessary, additional transducers can be added to achieve full coverage over 360 °. The two ultrasonic arrays 2 are rigidly attached to the surface of the system S. An alignment of the ultrasonic radiation 1 on the approaching missile 7.2 is carried out in the embodiment shown purely electronically via a corresponding phase control the individual ultrasonic transducer of an array 2. An additional, eg mechanical positioning is not necessary in this case.

Das System umfasst weiterhin vier elektrooptische Flugkörperwarnsensoren 4 zur Detektion eines Starts des feindlichen Flugkörpers (Bezugsziffer 7.1 zeigt den Flugkörper in der Startphase). Mit den gezeigten vier Sensoren 4 ist eine 360°-Abeckung möglich. Die dargestellten Flugkörperwarnsensoren 4 werden im vorliegenden Fall auch als Trackingsensoren zur Verfolgung des anfliegenden Flugkörpers verwendet.The system further comprises four electro-optical missile warning sensors 4 for detecting a launch of the enemy missile (reference number 7.1 shows the missile in the starting phase). With the four sensors 4 shown a 360 ° -Abeckung is possible. The illustrated missile warning sensors 4 are used in the present case as tracking sensors for tracking the approaching missile.

Das System nach Fig. 2 stellt eine sehr kompakte, leicht zu transportierende Baueinheit dar.The system after Fig. 2 represents a very compact, easy to transport unit.

Fig. 3 zeigt einen Ablaufplan für die Durchführung des erfindungsgemäßen Verfahrens. Fig. 3 shows a flowchart for carrying out the method according to the invention.

Der Start eines feindlichen Flugkörpers, z.B. einer Panzerabwehrgranate RPG-7, wird mit den Flugkörperwarnsensoren detektiert. Der Trackingsensor (dessen Funktion hier von den Flugkörperwarnsensoren wahrgenommen wird) übernimmt danach die Verfolgung des anfliegenden Flugkörpers. Mit der Positioniereinrichtung wird die abzustrahlende Ultraschallenergie auf den Flugkörper ausgerichtet. Die Ausrichtung erfolgt unter Berücksichtigung die Laufzeit des Ultraschallstrahls bis zum Ziel. Anschießend erfolgt die Erzeugung und gerichtete Abstrahlung der Ultraschallenergie in Form eines gebündelten, hochenergetischen akustischen Strahls. Im Falle einer rein elektrischen Ausrichtung fallen die Funktionen Ausrichtung und Abstrahlung der Ultraschallstrahlung zusammen.The launch of an enemy missile, e.g. an anti-tank grenade RPG-7, is detected with the missile warning sensors. The tracking sensor (whose function is perceived here by the missile warning sensors) then takes over the tracking of the approaching missile. The positioning device aligns the ultrasound energy to be radiated with the missile. The alignment takes into account the duration of the ultrasound beam to the target. Anschießend takes place the generation and directional radiation of the ultrasonic energy in the form of a bundled, high-energy acoustic beam. In the case of a purely electrical alignment, the functions of alignment and radiation of the ultrasonic radiation coincide.
