Abstract
Description
Die Erfindung bezieht sich auf ein Verfahren zur Erfassung, Verfolgung und Abwehr von Flugobjekten gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a method for the detection, tracking and defense of flying objects according to the preamble of claim 1.
Es ist z.B. aus Dokument DE-A 3 131 089 bekannt, im Gefechtsfeld mit mehreren an verschiedenen Standorten fest aufgestellten Waffensystemen eine zentrale Stelle mit einem Rundsuchsensor vorzusehen, der das gesamte Gefechtsfeld überwacht Werden feindliche Objekte geortet, dann werden Zieldaten dieser Objekte den Waffensystemen einzeln zugewiesen. Die voneinander abweichend Position von Rundsuchsensor und Waffensystem erfordert eine Zieldatentransformation, die auf den Standort des Waffensystems bezogen ist. Da die Ortskoordinaten fest installierter Waffensysteme im allgemeinen bekannt sind, haben die transformierten Zieldaten eine ausreichende Genauigkeit für eine Zielverfolgung bzw. für Abwehrmaßnahmen.It is e.g. It is known from document DE-A 3 131 089 to provide a central location in the battlefield with a number of weapon systems fixed at different locations with a round search sensor which monitors the entire battlefield. If enemy objects are located, target data of these objects are individually assigned to the weapon systems. The different position of the circular search sensor and weapon system requires a target data transformation that is related to the location of the weapon system. Since the location coordinates of permanently installed weapon systems are generally known, the transformed target data have sufficient accuracy for target tracking or for countermeasures.
Im Gefechtsfeld nicht ortsfest stationierte Waffensysteme erfordern für die Bestimmung der Standortkoordinaten unter Umständen einen erheblichen Aufwand. Als Standort eines mobilen Waffensystems kann nur in seltenen Fällen ein trigonometrisch vermessener Punkt im Gefechtsfeld, der die Vorraussetzung für eine genaue Transformation der vom Rundsuchsensor zugewiesenen Zieldaten auf den Standort ermöglichen würde, gewählt werden.Weapon systems that are not stationed stationary in the battlefield may require considerable effort to determine the location coordinates. As the location of a mobile weapon system, a trigonometrically measured point in the battlefield can only be selected in rare cases, which would enable the prerequisites for an exact transformation of the target data assigned by the search sensor to the location.
Der Erfindung liegt die Aufgabe zugrunde, bei einem Verfahren der eingangs genannten Art eine mit vertretbarem Aufwand im Gefechtsfeld durchführbare Standortbestimmung eines mobilen Waffensystems anzugeben, die eine Berechnung der auf den Standort bezogenen Zieldaten mit ausreichender Genauigkeit ermöglicht. Diese Aufgabe wird durch die kennzeichnenden Merkmale des Patentanspruchs gelöst.The invention is based on the object of specifying a location determination of a mobile weapon system which can be carried out with reasonable effort in the battlefield in a method of the type mentioned at the outset, which enables the target data relating to the location to be calculated with sufficient accuracy. This object is achieved by the characterizing features of the patent claim.
Die Aufschaltwahrscheinlichkeit wird durch Anwendung dieses Verfahrens wesentlich verbessert, da die bei der Standortbestimmung durch den Schlupf des Antriebes des Fahrzeuges gegenüber dem Erdboden unvermeidbaren Fehler zu einer unter Umständen erheblichen Verschlechterung der DatengOte führen können.The probability of activation is significantly improved by using this method, since the errors which are unavoidable when determining the location due to the slip of the drive of the vehicle relative to the ground can lead to a considerable deterioration in the data quality.
In der ersten Phase der Korrektur der Zieldaten durch Transformation auf den aktuellen Standort des Waffensystems wird unter Verwendung der von der Fahrzeugnavigationsanlage ermittelten mehr oder weniger fehlerbehafteten Standortkoordinaten mittels manueller Nachsteuerung des Folgesensors des Waffensystems eine Aufschaltung herbeigeführt und so die genauen Zielkoordinaten durch den Folgesensor ermittelt.In the first phase of the correction of the target data by transformation to the current location of the weapon system, using the more or less faulty location coordinates determined by the vehicle navigation system, an activation is carried out by means of manual readjustment of the sequence sensor of the weapon system and the exact target coordinates are determined by the sequence sensor.
Die Erfindung und weitere Einzelheiten der Erfindung werden anhand der Figuren 1 und 2 beispielhaft erläutert.The invention and further details of the invention are explained by way of example with reference to FIGS. 1 and 2.
Es zeigen
- Fig. 1 ein Feuerleitsystem mit einem zentralen Ortungsgerät und mehreren mobilen Waffensystemen mit je inem Folgesensor,
- Fig. 2 ein Blockschaltbild der Zieldatenverarbeitung in einem Waffensystem.
- 1 shows a fire control system with a central location device and several mobile weapon systems, each with a follow sensor,
- Fig. 2 is a block diagram of target data processing in a weapon system.
In einer zentralen Stelle wird mit einem Überwachungssensor (Suchradar) SR ständig die Luftlage im Gefechtsfeld ermittelt. Im Luftraum auftauchende Flugobjekte werden vom Überwachungssensor erfaßt und deren Zieldaten nach identifizierung über eine koordinierende Stelle KS einem von mehreren im Gefechtsfeld stationierten Waffensystemen WS1 bis WSn mit je einem Folgeradar FR übermittelt. Für alle weiteren Vorgänge ist eine Transformation der zugewiesenen Zieldaten auf den Standort des Waffensystems erforderlich, welche die Kenntnis der Standortkoordinaten voraussetzt.The air situation in the battlefield is continuously determined at a central point with a monitoring sensor (search radar) SR. Flying objects appearing in airspace are detected by the monitoring sensor and their target data, after identification via a coordinating point KS, is transmitted to one of several weapon systems WS1 to WSn stationed in the battlefield, each with a secondary radar FR. For all other processes, a transformation of the assigned target data to the location of the weapon system is required, which requires knowledge of the location coordinates.
Für eine erste Transformation mit angenäherten Daten F des Oberwachungssensors SR werden die Werte der Fahrzeugnavigationsanlage FNA verwendet. Die Fehler, die bei dieser Transformation nicht zu vermeiden sind, gehen auf Ungenauigkeiten der Messung der Fahrstrecke mittels der Fahrzeugnavigationsanlage FNA zurück, die durch den Schlupf des Antriebes entstehen. Diese Fehler wirken sich nachteilig auf die Datengenauigkeit und damit auf die Aufschaltwahrscheinlichkeit des Waffensystems aus. Durch wiederholtes Inniziieren der Standortbestimmung durch die Fahrzeugnavigationsanlage FNA können diese Fehler nur teilweise be hoben werden.The values of the vehicle navigation system FNA are used for a first transformation with approximated data F of the monitoring sensor SR. The errors that cannot be avoided with this transformation are due to inaccuracies in the measurement of the route by means of the vehicle navigation system FNA, which result from the slip of the drive. These errors have a detrimental effect on the data accuracy and thus on the probability of activation of the weapon system. These errors can only be partially remedied by repeatedly initiating the location determination by the vehicle navigation system FNA.
Um trotzdem mit den fehlerhaften Standortdaten der Fahrzeugnavigationsanlage FNA zu genauen Zieldaten zu kommen, wird ein am Fahrzeug des Waffensystems befindlicher Folgesensor FR mit den transformierten Daten auf das zugewiesene Ziel aufgeschaltet. Die vom Folgesensor FR mit sehr hoher Genauigkeit ermittelten Zieldaten werden dann mit den weiterhin von der zentralen Stelle gelieferten Daten des zugewiesenen Zieles verglichen. Die Differenz zwischen zugewiesenen Zieldaten und vom Folgesensor FR ermittelten Zieldaten wird abgespeichert und bei allen weiteren Zielzuweisungen und Zieldatentransformatonen als Korrekturwert berücksichtigt.In order nevertheless to arrive at exact target data with the incorrect location data of the vehicle navigation system FNA, a follow sensor FR located on the vehicle of the weapon system with the transformed data is applied to the assigned target. The target data determined by the follow sensor FR with very high accuracy are then compared with the data of the assigned target that is still supplied by the central point. The difference between the assigned target data and the target data determined by the follow sensor FR is stored and taken into account as a correction value for all further target assignments and target data transformations.
Das in Fig. 2 dargestellte Zielverfolgungssystem zeigt Blockschaltbild der Einrichtung für die elektronische Datenverarbeitung und Datenauswertung eines mobilen Waffensystems zur Abwehr von feindlichen Flugobjekten. Mit RR ist ein rundsuchendes Radar bezeichnet, das die Zielkoordinaten eines georteten Zielobjektes Z einem von mehreren mobilen Waffensystemen WS zuweist. Die fahrzeugeigene Einrichtung besteht aus einem Folgesensor FR, einer Fahrzeugnavigationsanlage FNA und einer Datenaufbereitung DA mit einer Anzeigeeinrichtung PPI.The target tracking system shown in FIG. 2 shows a block diagram of the device for electronic data processing and data evaluation of a mobile weapon system for the defense against enemy flying objects. With RR is a radar searching radar, which assigns the target coordinates of a located target object Z to one of several mobile weapon systems WS. The in-vehicle device consists of a following sensor FR, a vehicle navigation system FNA and a data preparation DA with a display device PPI.
In einem Rechner MP werden die von der Zentralstation zugewiesenen Zieldaten auf die durch die Fahrzeitnavigationsanlage FNA ermittelten Ortskoordinaten des Standortes des Waffensystems WS transformiert und als Zielobjekt auf dem Bildschirm der Anzeigeeinrichtung PPI dargestellt. Der Folgesensor FR wird nun mittels Rollkugel oder Steuerknüppel vom Bedienungspersonal auf das dargestellte Ziel aufgeschaltet. Der Folgesensor FR liefert während der Verfolgung des Zielobjektes Z sehr genaue Zieldaten, die in einem Komparator K mit den transformierten zugewiesenen Zieldaten verglichen werden. Der ermittelte Differenzwert Δ wird in einem Speicher SP abgelegt und bei allen weiteren Zielzuweisungen durch die zentrale Stelle (Rundsuchradar) RR vor allem nach einer Standort- änderung des Waffensystems WS als Korrekturwert für die Darstellung auf dem PPI berücksichtigtIn a computer MP, the target data assigned by the central station is transformed to the location coordinates of the location of the weapon system WS determined by the travel time navigation system FNA and is displayed as the target object on the screen of the display device PPI. The sequence sensor FR is now switched on by the operating personnel to the displayed target by means of a roller ball or control stick. The following sensor FR delivers Z while tracking the target object very precise target data, which are compared in a comparator K with the transformed assigned target data. The determined difference value Δ is stored in a memory SP and is taken into account as a correction value for the display on the PPI for all further target assignments by the central point (round search radar) RR, especially after a change in the location of the weapon system WS
