Abstract
Description
Die Erfindung geht aus von einer Kombinationsantenne gemäß dem Oberbegriff des Anspruches 1.The invention is based on a combination antenna according to the preamble of Claim 1.
Eine Antenne für den Einbau in das konische oder zylindrische Gehäuseteil eines Projektiles oder eines Wiedereintrittsflugkörpers ist in der US 4 305 078 A beschrieben. Se beruht auf einer dielektrischen Scheibe, deren Resonanzfrequenz mittels achsparalleler Kurzschlüsse zwischen ihren beiderseitigen elektrisch leitenden Kaschierungen induktiv beeinflußbar ist. Für mehrere Resonanzfrequenzen werden entsprechend viele solcher Scheiben, individuell abgestimmt, zu einem Sandwich gestapelt und elektrisch in Reihe geschaltet. Bei jeder der Scheiben handelt es sich um eine individuelle, rundum radial abstrahlende Schlitzantenne, weshalb auch eine solche mehrfache Antennengruppierung für einen auf die Bodenannäherung voraus ansprechenden Abstandszünder nicht verwendbar ist. Auch darf bezweifelt werden, daß es mit den wie dargestellt übereinstimmenden Abmessungen der Scheiben überhaupt möglich ist, größenordnungsmäßig so unterschiedliche Antennenfrequenzen wie für Navigationszwecke und für Zündradarzwecke zu realisieren.An antenna for installation in the conical or cylindrical housing part a projectile or a reentry missile is described in US 4,305,078. It is based on a dielectric disc, the resonance frequency of which means axially parallel short circuits between their mutually electrically conductive Laminations can be influenced inductively. For multiple resonance frequencies correspondingly many such slices, individually tailored, to form a sandwich stacked and electrically connected in series. Each of the disks is around an individual, radially radiating slot antenna, which is why a such multiple antenna grouping for one on the ground approach ahead appealing distance igniter is not usable. It can also be doubted that it matches the dimensions of the disks as shown is possible, so different antenna frequencies in the order of magnitude how to realize for navigation purposes and for ignition radar purposes.
Aus der DE 35 44 092 A1 sind GHz-Mehrbereichsantennen für kleine Suchköpfe in Projektilen bekannt, bei denen konzentrisch um eine Mittenachse gleichmäßig verteilt mindestens drei breitbandige Spiralantennen zum Empfang von Radarsignalen für das Abfangen von Radarbekämpfungs-Flugkörpern angeordnet sind; wobei im Zentrum der Spiralantennen mehrere Milimeterwellen-Antennen hinter einer dielektrischen Linse mit konstanter Dielektrizitätskonstante zusätzlich vorgesehen sind, um damit einen Dual-Mode-Suchkopf zu realisieren. DE 35 44 092 A1 describes GHz multi-range antennas for small seekers in Projectiles known to be distributed concentrically evenly around a central axis at least three broadband spiral antennas for receiving radar signals are arranged for intercepting radar-fighting missiles; being in Center of the spiral antennas several millimeter wave antennas behind a dielectric Lens with constant dielectric constant are additionally provided, to realize a dual-mode seeker head.
Aus der DE 24 08 578 C2 ist es als solches bekannt, aus einer quadratischen ebenen Leiterfläche und einer dazu parallelen leitenden Grundfläche eine Antennenstruktur für Abstrahlung oder Empfang elektromagnetischer Wellen im Mikrowellenspektrum zu erstellen, mit Anpassung auf eine mittlere Betriebswellenlänge mittels eines mittigen Einschnittes in mindestens eine der beiden Leiterflächenkanten in Richtung auf deren Mittelpunkt zu; wobei die Bandbreite dieser Antennenstruktur durch einen Einschnitt in mindestens eine Ecke der quadratischen Leiterflächen in Richtung ebenfalls zum Quadratmittelpunkt hin vergrößerbar ist.From DE 24 08 578 C2 it is known as such from a square plane Conductor surface and a parallel parallel base base an antenna structure for radiation or reception of electromagnetic waves in the microwave spectrum to create, with adjustment to a medium operating wavelength by means of a central one Incision in at least one of the two conductor surface edges in the direction of their center to; the bandwidth of this antenna structure by a Incision in at least one corner of the square conductor surfaces in the same direction can be enlarged towards the center of the square.
Aus der US 3 943 520 A ist eine zum Einbau in eine konisch sich verjüngende Umgebung geeignete dielektrische Keilantenne mit kapazitiver Abstimmung der Einspeisung gegenüberliegend an ihrem Scheitelbereich bekannt.From US 3 943 520 A is for installation in a conically tapered environment suitable dielectric wedge antenna with capacitive tuning of the feed opposite at its apex known.
Zur Leistungssteigerung einer Artillerierakete ist es aus der EP 0 840 393 A bekannt, auf der Außenmantelfläche des Raketenrumpfes ein dielektrisches Trägersubstrat für auf dessen Außenfläche gegeneinander versetzte und miteinander verkoppelte elektrisch leitende Flächen vorzusehen, die als Antennenstruktur für die Trägerfrequenz eines Navigationssatelliten ausgelegt sind.To increase the performance of an artillery rocket, it is known from EP 0 840 393 A on the outer surface of the missile fuselage, a dielectric carrier substrate for electrically offset and coupled to one another on its outer surface to provide conductive surfaces that act as an antenna structure for the carrier frequency of a navigation satellite are designed.
So sehr sich eine derartige Mantelflächen-Antenne für die Aufnahme von Satelliten-Ortungsinformationen auch schon bewährt hat, weist sie doch den Nachteil auf, in Hinblick auf die mechanische Beanspruchung bei der Verbringung aus einem Rohr nicht problemlos ohne weiteres - insbesondere auch nachträglich noch - auf dem Projektil appliziert werden zu können.So much for such a surface antenna for the recording of satellite location information has already proven itself, as it has the disadvantage in With regard to the mechanical stress when moving from a pipe not without problems without further ado - especially afterwards - on the Projectile can be applied.
Vorliegender Erfindung liegt die technische Problemstellung zugrunde, einen Annäherungszünder für ein Artillerieprojektil hinsichtlich seiner Antennenstruktur derart auszulegen, dass sie auch für Aufgaben der Satellitennavigation nutzbar und an der eingeführten Artilleriemunition problemlos nachrüstbar ist.The present invention is based on the technical problem, a proximity fuse for an artillery projectile in terms of its antenna structure interpret that they can also be used for satellite navigation tasks and at the imported artillery ammunition can be easily retrofitted.
Diese Aufgabe ist ausweislich der Merkmalskombination des Hauptanspruches im wesentlichen dadurch gelöst, daß die unter der Ogive des Annäherungszünders gelegene Antenne in als solcher bekannter Weise als dielektrische Scheibe ausgebildet und auf eine Radarfrequenz abgestimmt ist, die zugleich der dritten Oberwelle des Trägers eines Systems von Navigationssatelliten ist. This task is evidenced by the combination of features of the main claim in essentially solved in that the one located under the ogive of the proximity fuse Antenna formed in a manner known as such as a dielectric disc and is tuned to a radar frequency that is also the third harmonic of the Carrier of a system of navigation satellites.
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 exchangeable. 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 carrier 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 Multifunktionszünders 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 Navigationsantenne 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 surface area of the projectile inside the projectile tip, however, insofar as the Top of a modern artillery detonator like 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, what 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.So with a high degree of integration via a frequency coupling, GPS reception is all in one 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 winnable.
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. In der Zeichnung zeigt:

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 19 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
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
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
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
