Description

Peilverfahren, durch welches eine eindeutige Richtungsanzeige über 360° erzielt wird Eine Reihe der bisher bekannt gewordenen direkt zeigenden Peilverfahren arbeitet mit zwei Empfangssystemen, deren verstärkte Empfangsströme entweder gleichzeitig oder periodisch wechselnd auf den Indikator einwirken. Beeinflussen beide Empfangssysteme gleichzeitig den Indikator, so sind zwei Verstärkeranordnungen notwendig, die genau gleicheVerstärkungszahlen aufweisen m'ü'ssen. Die Herstellung von Verstärkern, die betriebsmäßig gleiche Verstärkerzahlen aufweisen, bringt einige Schwierigkeiten mit sich, so daß u. a. auch wegen der notwendigen doppelten Verstärkungsanordnung direkt zeigende Peilgeräte, deren Empfangsströme periodisch wechselnd auf den Indikator einwirken, bevorzugt werden. Um diese periodische Umschaltung der Hochfrequenzströme, die bei Empfang schwacher Energien mit praktischen Schwierigkeiten verbunden sein kann, zu vermeiden, ist ein anderes auf Phasenmessungen beruhendes Peilverfahren bereits vorgeschlagen worden. Dieses Verfahren arbeitet mit einem kontinuierlich gedrehten Empfangsrahmen. Die im Rahmen induzierte Hochfrequenz wird im Empfänger gleichgerichtet. Infolge der Rotation des Rahmens stellt der gleichgerichteteEmpfangsstrom einen Wellenstrom dar. Die Wechselstromkomponente des Wellenstromes besitzt infolge der bei jeder Rahmendrehung durchlaufenen Empfangsminima und Empfangsmaxima eine Frequenz, die doppelt so groß ist wie die Rahmendrehzahl. Durch einen mit der Rahmendrehachse verbundenen vierpoligen Wechselstromgenerator wird ein Hilfswechselstrom erzeugt, dessen Frequenz ebenfalls gleich der doppelten Drehzahl, also gleich der Frequenz der Empfangswechselstromkomponente ist. Die Messung der Phase zwischen der Empfangswechselstromkomponente und dem synchronen Hilfsstrom ergibt dann bis auf die Unbestimmtheit von i8o° die Richtung der einfallenden Strahlen. Ist der Peilempfänger dabei beispielsweise auf einem beweglichen Fahrzeug aufgestellt, so bleibt es unsicher, ob der Sender voraus oder achtern liegt.DF method through which a clear directional indication is given 360 ° is achieved A number of the previously known direct-pointing direction finding methods works with two receiving systems, whose amplified receiving streams either simultaneously or act periodically alternating on the indicator. Influence both receiving systems at the same time the indicator, so two amplifier arrangements are necessary that exactly must have the same amplification numbers. The manufacture of amplifiers that have the same number of amplifiers operationally, brings some difficulties with itself, so that i.a. also because of the necessary double reinforcement arrangement direct-pointing direction finders whose received currents change periodically on the indicator act, be preferred. To this periodic switching of the high frequency currents, which are associated with practical difficulties in receiving weak energies Another DF method based on phase measurements can be avoided has already been proposed. This process works on a continuous basis rotated receive frame. The high frequency induced in the frame is used in the receiver rectified. As a result of the rotation of the frame, the rectified receive current is set represents a wave current. The alternating current component of the wave current has as a result of the reception minima and reception maxima passed through with each frame rotation Frequency that is twice the frame speed. By one with the frame rotation axis connected four-pole alternator, an auxiliary alternating current is generated, its frequency also equal to twice the speed, i.e. equal to the frequency is the receiving AC component. The measurement of the phase between the received AC component and the synchronous auxiliary current, except for the uncertainty of i8o °, results in the Direction of the incident rays. For example, if the DF receiver is on If a moving vehicle is set up, it remains uncertain whether the transmitter is ahead or aft.

Die vorliegende neue Erfindung beseitigt diesen :C7belstand und gestattet an einem über einer 36o° Skala einspielenden Zeiger unmittelbar und eindeutig die Richtung der einfallenden Wellen abzulesen. Eine grundsätzliche Schaltskizze des neuen Verfahrens ist in der Abbildung wiedergegeben. Dem Hochfrequenzstrom, der bei Empfang in einer ungerichteten Antenne d fließt, wird der Hochfrequenzstrom, der in einer Rahmenantenne b auftritt, die um eine vertikale Achse c von einem Motor d gedreht wird, überlagert. Die Stromzuführung zu dem Rahmen kann dabei über die Schleifringe und Schleifbürsten e oder über einen rotierenden Kondensator erfolgen. Der Superpositionsstrom wird in einem angeschlossenen Empfänger, im einfachsten Falle einem Detektor f, gleichgerichtet. Wenn dei# Rahmen rotiert, entsteht bei jeder Umdrehung des Rahmens infolge des kardioidischen Empfangsdiagramms nur ein Minimum und nur ein Maximum in dem gleichgerichteten Wellenstrom. Auf der Rotationsachse c sitzt ein Wellenstrom- oder Drehstromgenerator g. Der von diesem gelieferte Strom hat eine Frequenz, die gleich der Rahmendrehzahl ist. Mit diesem Hilfsstrom wird das Feld eines Phasenmessers h gespeist, während an das bewegliche System des Phasenmessers der Empfangsstrom gelegt wird. Zu jeder möglichen horizontalen Richtung der einfallenden Wellen gehört eine zugeordnete, zwischen o und 36o° liegende Phasenverschiebung zwischen dem Strom im beweglichen System des Phasenmessers und dem das Statorfeld des Phasenmessers erzeugenden Strom. Es kann somit die Richtung der einfallenden Wellen unmittelbar und eindeutig an dem Zeiger des Phasenmessers abgelesen werden.The present new invention eliminates this problem and allows on a pointer moving in over a 36o ° scale directly and unambiguously the Read the direction of the incoming waves. A basic circuit diagram of the new procedure is shown in the figure. The high frequency current that when receiving in an omnidirectional antenna d flows, the high-frequency current, which occurs in a loop antenna b, which is about a vertical axis c of a motor d is rotated, superimposed. The power supply to the frame can be via the Slip rings and brushes e or via a rotating capacitor. The superposition current will in a connected receiver, in the simplest case a detector f, rectified. When the frame rotates arises with each revolution of the frame as a result of the cardioid reception diagram only a minimum and only a maximum in the rectified wave current. On the Axis of rotation c sits a shaft current or three-phase generator g. The one from this one The current supplied has a frequency that is equal to the frame speed. With this Auxiliary power is fed to the field of a phase meter h, while to the movable System of the phase meter the receive current is placed. At every possible horizontal The direction of the incident waves belongs to an assigned one lying between 0 and 36o ° Phase shift between the current in the moving system of the phase meter and the current generating the stator field of the phase meter. It can thus determine the direction of the incident waves directly and clearly on the phaser pointer can be read.
