Description

Die Erfindung betrifft ein Projektil gemäß dem Oberbegriff des Anspruches 1.The invention relates to a projectile according to the preamble of claim 1.

Das gattungsbildende Projektil ist aus der EP-A-0 840 393 als leistungsgesteigerte Artillerie-Rakete bekannt, die auf der Außenmantelfläche ihres Rumpfes ein dielektrisches Trägersubstrat für auf dessen Außenfläche gegeneinander versetzte und miteinander gekoppelte elektrisch leitende Flächen aufweist, die als Antennenstruktur für die Trägerfrequenz von Navigationssatelliten ausgelegt sind.The generic projectile is from EP-A-0 840 393 as a performance-enhanced artillery rocket known that a dielectric carrier substrate on the outer lateral surface of their fuselage for electrically offset and coupled with one another on its outer surface has conductive surfaces that act as an antenna structure for the carrier frequency of navigation satellites are designed.

So sehr sich diese Mantelflächen-Antenne für die Aufnahme von Satelliten-Ortungsinformationen auch schon bewährt hat, weist sie doch den Nachteil auf, im Hinblick auf die mechanische Beanspruchung beim Abschuß aus dem Waffenrohr nicht problemlos ohne weiteres - insbesondere auch nachträglich noch - auf dem Projektil appliziert werden zu können.So much for this lateral surface antenna for the recording of satellite positioning information has already proven itself, it has the disadvantage, in terms of on the mechanical stress when firing from the gun barrel is not without problems can be easily applied to the projectile - especially afterwards to be able to.

Vorliegende Erfindung liegt deshalb die technische Problemstellung zugrunde, ein Projektil gattungsgemäßer Art derart auszulegen, daß seine Empfangsantenne einerseits gegen die mechanischen Beanspruchungen beim Abschuß des Projektils aus einem Waffenrohr besser geschützt und andererseits problemlos auch nachrüstbar ist; wobei ferner die Option eröffnet werden soll, die Satellitennavigations-Empfangsantenne auch für andere Aufgaben nutzen zu können.The present invention is therefore based on the technical problem, a projectile Generic type to be interpreted in such a way that its receiving antenna on the one hand against the mechanical Stresses better protected when shooting the projectile from a gun barrel and on the other hand can also be easily retrofitted; the option also being opened to use the satellite navigation receiving antenna for other tasks can.

Diese Aufgabe ist ausweislich der Merkmale im Kennzeichnungsteil des Hauptanspruches bei einem gattungsgemäßen Projektil erfindungsgemäß im wesentlichen dadurch gelöst, daß die Antenne unter dessen Ogive verlegt ist, wo die elektrisch leitenden Flächen beiderseits auf eine quer zur Längsachse des Projektils konzentrisch angeordneten dielektrischen Trägerscheibe aufgebracht sind. This task is evidenced by the features in the labeling part of the main claim a generic projectile according to the invention essentially solved in that the Antenna is placed under the ogive, where the electrically conductive surfaces are on both sides a dielectric carrier disk arranged concentrically to the longitudinal axis of the projectile are upset.

Die Spitze eines modernen Artillerieprojektils enthält gewöhnlich in Flugrichtung hinter einer konzentrisch angeordneten Programmierspule einen Schaltungsmodul mit wenigstens einem Signalprozessor für die Auswerteelektronik, und dahinter Sicherungs- und Zündeinrichtungen. Da die Spitze mit dem Rumpf des Projektils verschraubt ist, um sie erst im Einsatzfall aufzubringen, ist sie auch unproblematisch austauschbar. Es erweist sich, daß in dem sich nach vorne hin verjüngenden Innenraum der Spitze ist unmittelbar vor der Spule noch Freiraum zum zusätzlichen Einbau der Trägerscheibe für die Antennenstruktur des Navigationsempfängers ist. Der Empfänger selbst, also die Signalverarbeitung zum Gewinnen und Auswerten der Satelliten-Navigationsinformation kann in den hinter der Spule gelegenen Modul einbezogen werden.The tip of a modern artillery projectile usually contains in the direction of flight behind one concentrically arranged programming coil a circuit module with at least one Signal processor for the evaluation electronics, and behind it fuse and ignition devices. Since the tip is screwed to the fuselage of the projectile, it is only used when it is in use to apply, it is also easily interchangeable. It turns out that in the the interior of the tip tapering towards the front is still free space immediately in front of the coil for additional installation of the carrier plate for the antenna structure of the navigation receiver is. The receiver itself, i.e. the signal processing for winning and The satellite navigation information can be evaluated in the module located behind the coil be included.

Die Antennenstruktur, also die Geometrie der elektrisch leitenden Flächen auf den beiden Seiten der dielektrischen Trägerscheibe, ist vorzugsweise in Bezug auf die Rotationsachse des Projektils so ausgelegt, daß sich ein punktsymmetrisches Antennendiagramm einstellt, um rotationsabhängige Störeinflüsse wie insbesondere Amplitudenmodulationen der Empfangssignale möglichst zu vermeiden.The antenna structure, i.e. the geometry of the electrically conductive surfaces on the two Sides of the dielectric support disc, is preferably in relation to the axis of rotation of the Projectile designed in such a way that a point-symmetrical antenna pattern is set to rotation-dependent interferences such as, in particular, amplitude modulations of the received signals to avoid if possible.

Problematisch kann die Absicht einer Verlagerung der Navigations-Empfangsantenne von der Mantelfläche des Projektils ins Innere der Projektilspitze allerdings insofern werden, als die Spitze bei einem modernen Artilleriezünder wie im Falle des eingeführten Multifünktionszünders DM74 vor der Programmierspule schon mit einer koaxial stehenden Dipol- oder Helix-Radarantenne für das Abstands-Zündkriterium ausgestattet ist, was räumliche und elektrische Einschränkungen in den Antennenfunktionen zu Folge hat. Gemäß einer Weiterbildung vorliegender Erfindung wird dieses Problem aber dadurch beherrscht, daß die Navigations-antenne für die dritte Oberwelle der Satelliten-Trägerfrequenz und damit für die Größenordnung der Trägerfrequenz eines üblichen Radar-Entfernungsmessers ausgelegt wird. Dann erübrigt sich die zusätzliche Radar-Dipolantenne, und die flachzylindrisch-scheibenförmige Antennenstruktur dient beiden Systemen (Navigationsempfänger und Entfernungsradar) als Antennensystem. Nun ist es allerdings zweckmäßig, zur Vermeidung wechselseitiger Störungen eine Entkoppelung vorzunehmen, die am einfachsten dadurch erfolgt, daß der Navigationsempfänger und das Radar nicht gleichzeitig betrieben werden. Das ist unproblematisch realisierbar, weil die Satellitennavigation lediglich für die Bahnvermessung (zur Bahnkorrektur) benötigt wird, während das Radar erst anschließend, nach Ankunft über dem Zielgebiet beim Abstieg zur Abstandsauslösung über Grund arbeiten muß. The intention to relocate the navigation reception antenna from the The outer surface of the projectile inside the projectile tip, however, insofar as the Top in a modern artillery detonator as in the case of the introduced multi-function detonator DM74 in front of the programming coil with a coaxial dipole or helix radar antenna is equipped for the distance ignition criterion, which is spatial and electrical Results in restrictions in the antenna functions. According to further training In the present invention, this problem is mastered in that the navigation antenna for the third harmonic of the satellite carrier frequency and thus for the order of magnitude the carrier frequency of a conventional radar range finder is designed. Then unnecessary the additional radar dipole antenna, and the flat cylindrical disc-shaped one Antenna structure serves as both systems (navigation receiver and range radar) Antenna system. Now, however, it is advisable to avoid mutual interference to perform a decoupling, which is most easily done by the navigation receiver and the radar cannot be operated simultaneously. That is not a problem feasible because the satellite navigation only for the orbit measurement (for orbit correction) is needed, while the radar is only then after arriving over the target area must work on the ground when descending to trigger the distance.

So ist bei hohem Integrationsgrad über eine Frequenzkopplung der GPS-Empfang in einem Radarannäherungszünder ermöglicht, ohne daß Raum für getrennte Antennen benötigt wird, also auf engstem Raum mit derselben Antenne die Navigationsinformation und das Radarecho gewinnbar.With a high degree of integration, GPS reception is all in one via frequency coupling Radar proximity detonator enables without the need for space for separate antennas So in a confined space with the same antenna, the navigation information and the radar echo recoverable.

Zusätzliche Weiterbildungen und weitere Vorteile der Erfindung ergeben sich aus den weiteren Ansprüchen und aus nachstehender Beschreibung eines in der Zeichnung unter Beschränkung auf das Funktionswesentliche nicht ganz maßstabsgerecht skizzierten prinzipiellen Realisierungsbeispiels für die erfindungsgemäße Lösung.

The drawing shows:

Die in Fig. 1 in abgebrochener Darstellung und teilweise im Achsial-Längsschnitt skizzierte Spitze 11 eines Artillerie-Projektiles 12 trägt vor ihrem metallischen Gehäuse 13 eine ballistische Haube 14 in Form eines für Hochfrequenz durchlässigen Kunststoff-Radom aus thermoplastischem Werkstoff wie Teflon. Die Ebene der Teilungsfuge zwischen Gehäuse 13 und Haube 14 wird vom Schaltungsmodul 15 für verschiedene Signalverarbeitungsaufgaben durchragt, der in Projektil-Flugrichtung vor sich unter der Radom-Haube 14 eine großflächige Programmierspule 16 für die Zündfunktion des Schaltungsmodus 15 trägt. Im hohlkegelförmigen Innenraum der Haube 14 vor der Programmierspule 16 ist an sich die Dipol- oder Helixstruktur der Sende-Empfangs-Antenne 17 eines Abstands-Radar 18 (Fig. 2) angeordnet. Diese Radarantenne 17 ist nun aber als Dualmode-Planarantenne konzentrisch vor der Programmierspule 16 ausgebildet, da sie zugleich als Empfangsantenne 19 eines Satelliten-Navigationsempfängers 20 dient. Die Radar-Antenne 17 und die Navigations-Antenne 20 sind also zu einer Kombinationsantenne 21 auf einer etwa 2,5 mm dicken Scheibe (bei etwa zehnfachem Durchmesser) zusammengefaßt, deren Kaschierung auf Resonanz bei der zwischen 4 GHz und 5 GHz liegenden Radarfrequenz im C-Band abgestimmt ist. Damit ist sie zugleich auf die dritte Harmonische der bei 1,5 MHz liegenden L1-Trägerfrequenz der Satellitennavigation abgestimmt, so daß die Kombinationsantenne 21 gleichzeitig sowohl für den Betrieb des Radars 18 sowie auch für den Betrieb des Navigationsempfängers 20 optimiert ist. The sketched in Fig. 1 in broken view and partially in axial longitudinal section Tip 11 of an artillery projectile 12 carries a ballistic in front of its metallic housing 13 Hood 14 in the form of a high-frequency permeable plastic radome made of thermoplastic Material like Teflon. The level of the joint between housing 13 and Hood 14 is used by circuit module 15 for various signal processing tasks protrudes through a large area in the projectile flight direction in front of it under the radome hood 14 Programming coil 16 for the ignition function of the circuit mode 15 carries. In the hollow cone The interior of the hood 14 in front of the programming coil 16 is in itself the dipole or helix structure the transmit / receive antenna 17 of a distance radar 18 (FIG. 2) is arranged. This radar antenna 17 is now concentric in front of the programming coil as a dual-mode planar antenna 16 trained because they are also the receiving antenna 19 of a satellite navigation receiver 20 serves. The radar antenna 17 and the navigation antenna 20 are thus to a combination antenna 21 on an approximately 2.5 mm thick disc (at approximately ten times Diameter), the lamination of which resonates between the 4th GHz and 5 GHz radar frequency in the C-band is tuned. With that she is at the same time to the third harmonic of the L1 carrier frequency of satellite navigation at 1.5 MHz matched so that the combination antenna 21 simultaneously for both operation of the radar 18 and also for the operation of the navigation receiver 20 is optimized.

Die Kombinationsantenne 21 ist als dielektrische Flachantenne aufgebaut, die auf den beiden einander gegenüberliegenden Oberflächen einer beispielsweise kreisscheibenförmigen dielektrischen Trägerscheibe 22 (in der Zeichnung zur Veranschaulichung übertrieben dick skizziert) elektrisch leitende Flächenstrukturen trägt, die beispielsweise aus einer ursprünglich flächendeckenden Kaschierung herausgeätzt sind. Die Scheiben-Kaschierung besteht aus einer vorderseitigen Fläche 24.1 und einer in allen Richtungen über ihre Begrenzung hinausgehenden rückseitigen Fläche 24.2. Für die Ausbildung einer zur Geschoßachse 23 symmetrischen Antennencharakteristik ist die Trägerscheibe 22 konzentrisch quer zur Achse 23 vor der Programmierspule 16 gehaltert.The combination antenna 21 is constructed as a dielectric flat antenna, based on the two mutually opposite surfaces of a circular dielectric, for example Carrier disc 22 (exaggeratedly thick in the drawing for illustration) carries electrically conductive surface structures, for example from an original extensive lamination are etched out. The window lamination consists of a front surface 24.1 and one in all directions beyond its boundary back surface 24.2. For the formation of a symmetrical to the projectile axis 23 Antenna characteristic is the carrier disc 22 concentrically transverse to the axis 23 in front of the Programming coil 16 held.

Um den Betrieb des Abstandsradars 18 für die Zündauslösung und des Navigationsempfängers 20 für die Bahnkorrektur von einander zu entkoppeln, speist die Kombinationsantenne 21 entweder das Radar 18 oder den Navigationsempfänger 20, aber nicht beide gleichzeitig, was in Fig.2 durch einen Umschalter 25 symbolisiert ist, der im Interesse möglichst geringen Signalverlustes vorzugsweise als PIN-Diodenschalter realisiert ist. Diese Umschaltung erfolgt aus einer Steuerstufe 26 nach Maßgabe der über die induktive Schnittstelle an der Spule 16 vorgegebenen Programmierung des Einsatzes des Radarbetriebes erst in der Schlußphase der Mission, also nach vorgebbarer Mindestflugzeit. Bis zum Einsatz des Radarbetriebes, also auf der Verbringungsflugbahn, wird dagegen der Navigationsempfänger 20 an die Kombinationsantenne 21 angeschlossen, um die aktuelle Flugbahn mit Hilfe der Satellitennavigation aufnehmen oder erforderlichenfalls korrigieren zu können.To operate the distance radar 18 for the ignition trigger and the navigation receiver 20 to decouple from each other for the path correction feeds the combination antenna 21 either the radar 18 or the navigation receiver 20, but not both at the same time what is symbolized in FIG. 2 by a changeover switch 25 which, in the interest of the least possible signal loss is preferably implemented as a PIN diode switch. This switchover takes place from a control stage 26 in accordance with the inductance at the coil 16 predetermined programming of the use of the radar operation only in the final phase of Mission, i.e. after a predefinable minimum flight time. Until the use of radar operation, i.e. on the movement trajectory, on the other hand, the navigation receiver 20 is connected to the combination antenna 21 connected to record the current trajectory using satellite navigation or to be able to correct it if necessary.

Das erfindungsgemäß ausgestattete Projektil 12 trägt also in seiner austauschbaren Spitze 11 unter ihrer ballistischen Radom-Haube 14 eine einfach integrierbare Kombinationsantenne 21 mit hemisphärischer Sicht in Flugrichtung voraus, deren Abstimmung sowohl der Grundfrequenz des Radars 17 eines Abstandszünders wie auch der dritten Oberwelle der Trägerfrequenz eines Satelliten-Navigationsempfängers 20 entspricht, so daß über diese eine Kombinationsantenne 21 beide Systeme auf engstem Raum betrieben werden können. Zur Entkopplung ist vorgesehen, daß das Abstandsradar 18 erst in Betrieb genommen wird, wenn der Navigationsempfänger 20 abgeschaltet ist, weil das Projektil 12 auf seiner korrigierten Flugbahn über dem Zielgebiet angekommen ist.The projectile 12 equipped according to the invention thus has a replaceable tip 11 under its ballistic radome hood 14 is an easily integrated combination antenna 21 with a hemispherical view in the direction of flight ahead, the tuning of both the fundamental frequency of the radar 17 of a distance igniter as well as the third harmonic of the carrier frequency corresponds to a satellite navigation receiver 20, so that a combination antenna 21 both systems can be operated in a confined space. For decoupling it is provided that the distance radar 18 is only put into operation when the navigation receiver 20 is switched off because the projectile 12 is corrected on its Trajectory has reached the target area.
