Abstract
Description
Die Erfindung betrifft eine Vorrichtung gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a device according to the preamble of claim 1.
Das Zentrum einer Unterbrecherscheibe, die für Strahlen durchgängige und unterbrechende Segmente aufweist, wird auf einer nutierenden Kreisbahn um ein definiertes Sehfeld bewegt. Das zu ortende Objekt wird auf der Modulatorscheibe "abgebildet" (siehe z.B. DE-PS 29 44 261).The center of a breaker disc that is continuous and for rays has interrupting segments, is on a nutating circular path moved around a defined field of view. The object to be located is on the Modulator disc "shown" (see e.g. DE-PS 29 44 261).
Strahlung, die am Rande des Sehfeldes auftrifft, wird bei jedem Umlauf einmal mit der niedrigsten, einmal mit der höchsten Frequenz moduliert. Der entstehende Frequenzhub ist also ein Maß für die Ablage. Im Zentrum des Sehfeldes stellt sich die mittlere Frequenz der Modulatorscheibe ein (abh. von Drehzahl und Stegzahl).Radiation that strikes the edge of the field of view is emitted with every revolution modulated once with the lowest, once with the highest frequency. The resulting frequency swing is therefore a measure of the storage. Downtown The mean frequency of the modulator disc is established in the field of view (depending on speed and number of webs).
Der Nachteil des Systems besteht darin, daß eine relativ große Modula tionsbandbreite (und eine dementsprechend große Signalverarbeitungsband breite) starr vorgegeben ist, obwohl sie bei den bekannten Flugkörper systemen nur zu max. 15% der "Missionszeit" genützt wird.The disadvantage of the system is that it has a relatively large modulus tion bandwidth (and a correspondingly large signal processing bandwidth latitude) is fixed, although it is used in the known missiles systems only to max. 15% of the "mission time" is used.
Die Aufgabe der Erfindung ist es, die zu verarbeitenden Signalbandbrei ten zu verringern und die Störsicherheit zu erhöhen.The object of the invention is to process the signal bandwidth reduce and increase immunity to interference.
Die Erfindung beschreibt eine Lösung, die darin besteht, daß sie den er forderlichen Frequenzhub der Lage des Flugkörpers im Sehfeld anpaßt. The invention describes a solution which consists in the fact that it adapts required frequency shift of the position of the missile in the field of view.
Die Vorteile dieser Anordnung sind:The advantages of this arrangement are:
- - eine optimale Anpassung der Stegbreite des Modulators an die der jeweiligen Flugphase entsprechenden Flugkörper-Abbildung,- An optimal adaptation of the web width of the modulator to that of missile mapping corresponding to the respective flight phase,
- - eine bessere Unterdrückung von Strahlungsquellen, die größer als der Flugkörper-Durchmesser sind,- better suppression of radiation sources larger than that Missile diameters are
- - eine geringere Verarbeitungsbandbreite.- a lower processing bandwidth.
Ein vorteilhafter Nebeneffekt dieser Anordnung ist die gleichzeitige Dämpfung von Störstrahlungsquellen außerhalb des zu modulierenden Seh feldes durch das Zentrum der Modulationsscheibe.An advantageous side effect of this arrangement is the simultaneous Attenuation of interference radiation sources outside of the vision to be modulated field through the center of the modulation disc.
Der Antrieb der Modulatorscheibe 5 erfolgt durch Rotation dieser Scheibe um ihre Achse 7, über einen Exzenter 6. Die Neuerung besteht darin, daß der Exzenter-Weg (Hub 1) veränderbar ist. Der Radius der Nutation 14, bezogen auf Sehfeldmitte (optische Achse 8) verändert sich gleichermaßen.The modulator disc 5 is driven by rotating this disc about its axis 7 , via an eccentric 6 . The innovation is that the eccentric path (stroke 1 ) can be changed. The radius of the nutation 14 , based on the center of the field of view (optical axis 8 ) changes in the same way.
Damit besteht die Möglichkeit, die Stegbreite der Segmente 12, 13 in der Mitte des Sehfeldes der jeweiligen Abbildung des Flugkörpers optimal an zupassen, insbesondere durch ihre sektorförmige Ausbildung.This makes it possible to optimally adapt the web width of the segments 12 , 13 in the middle of the field of view to the respective image of the missile, in particular by means of their sector-shaped design.
Damit kann gegenüber im Stand der Technik verwendeten unveränderlichen Stegbreiten eine größere Störunterdrückung (Hintergrundstrahlung und großflächige Störer) erzielt werden.This can be invariable compared to the state of the art Bridge widths a larger interference suppression (background radiation and large-scale interferers) can be achieved.
Die Mittenfrequenz erhöht sich hierbei entsprechend der Stegbreitenver ringerung an dieser Stelle. Insgesamt wird der Modulationshub geringer, weil die niedrigen Frequenzen hier außerhalb 4 des Sehfeldes 3 liegen, während die hohen Frequenzen innerhalb 2 liegen. The center frequency increases according to the bridge width reduction at this point. Overall, the modulation swing becomes smaller because the low frequencies here lie outside 4 of the field of view 3 , while the high frequencies lie within 2 .
Die höchste Modulationsfrequenz bleibt gleich, nur ist sie jetzt einem kleineren Sehfelddurchmesser (Radius) zugeordnet.The highest modulation frequency remains the same, only it is now one assigned smaller field of view diameter (radius).
Zur Gewinnung der Ablagespannungen mittels (über die Immersionsoptik 10 und die Photozelle 11 erfolgende) Detektorsignalauswerteschaltung zur Führung bzw. Lenkung des FK gibt es zwei Verfahren:There are two methods for obtaining the storage voltages by means of detector signal evaluation circuit (via the immersion optics 10 and the photocell 11 ) for guiding or steering the LC:
- a) Der Demodulator wird in der Mittenfrequenz nachgeführt. Verfahren hierzu sind bekannt. Die Ablagespannung ist dann die Summe aus dem Differenz-, Mittenfrequenz-Signal und dem demodulierten Frequenzhub.a) The demodulator is tracked in the center frequency. method this is known. The storage voltage is then the sum of the Difference, center frequency signal and the demodulated frequency swing.
- b) Die Drehzahl der Modulationsscheibe wird analog zum Exzenter-Hub z.B. von einem stufenlos regelbaren Antrieb (M) herabgesetzt. Die Mittenfrequenz bleibt dann konstant. Der Vorteil dieser Anordnung besteht darin, daß die obere Modulationsfrequenz herabgesetzt wird. Die Ablagespannung wird dann aus einem der Motorregelspannung abge leiteten Signal und dem demodulierten Frequenzhub gebildet.b) The speed of the modulation disc is reduced analogously to the eccentric stroke, for example by a continuously variable drive ( M ). The center frequency then remains constant. The advantage of this arrangement is that the upper modulation frequency is reduced. The storage voltage is then formed from a signal derived from the motor control voltage and the demodulated frequency swing.
In Verbindung mit einem vorteilhaft zur Erzeugung des optischen Strah lenbündels 9 getasteten Strahler ergibt sich der Vorteil, daß die Tast frequenz und das obere Seitenband der Modulation in einem niedrigeren Frequenzbereich liegen.In connection with an advantageous to generate the optical beam lenbastel 9 radiator has the advantage that the scanning frequency and the upper sideband of the modulation are in a lower frequency range.
