Description
Die Erfindung betrifft ein Verfahren zur Echtzeit-Geländeaufklärung gemäß dem
Oberbegriff des Anspruches 1 und eine Vorrichtung zur Durchführung dieses
Verfahrens gemäß dem Oberbegriff des Anspruches 7.The invention relates to a method for real-time terrain reconnaissance according to the
Preamble of
Üblicherweise wird zur Echtzeit-Geländeaufklärung und zum Erfassen von Meßdaten wie der Lufttemperatur, der Windrichtung usw. eine kombinierte Bild- und Tonübertragung mit analogen Signalen vorgenommen. Um Meßdaten wie die Lufttemperatur o.dgl. beispielsweise aus einem Geschoß oder einem Flugkörper zusätzlich zu den Bildsignalen des aufzuklärenden Geländes vom Aufklärungs-Flugkörper zu einem Empfänger einer Bodenstation zu übertragen, kann der Tonträger benutzt werden, indem die quasi skalaren Meßdaten diesem aufmoduliert werden. Das ist jedoch nur mit einer eingeschränkten Bandbreite von ca. 40 kBit/sec bei NRZ-Daten (non return to zero), d.h. bei gängigen bipolaren, binär kodierten Digitalsignalen möglich. Eine andere Möglichkeit besteht darin, für die Bildsignalübertragung und für die Meßdaten-Signalübertragung zwei voneinander verschiedene Trägerfrequenzen zu verwenden. Die Verwendung von zwei voneinander verschiedenen Trägerfrequenzen stellt jedoch eine Verschwendung der nur eingeschränkt zur Verfügung stehenden Frequenzbänder dar. Die Verwendung zweier getrennter Trägerfrequenzen bedingt außerdem einen erheblichen Aufwand, weil für diese voneinander verschiedenen Trägerfrequenzen beispielsweise geeignete Antennen erforderlich sind.Usually, real-time terrain surveillance and the acquisition of measurement data such as air temperature, wind direction, etc. a combined image and Sound transmission made with analog signals. To measure data like that Air temperature or the like for example from a floor or a missile in addition to the image signals from the reconnaissance missile The sound carrier can transmit to a receiver of a ground station be used by modulating the quasi-scalar measurement data on it. The is, however, only with a restricted bandwidth of approx. 40 kbit / sec for NRZ data (non return to zero), i.e. with common bipolar, binary coded digital signals possible. Another possibility is for the image signal transmission and for the measurement data signal transmission to two different carrier frequencies use. The use of two different carrier frequencies however, is a waste of the limited available Frequency bands represent the use of two separate carrier frequencies also a considerable effort because they differ from each other Carrier frequencies, for example, suitable antennas are required.

Der mindestens eine Sensor und das Relais sind als mit Abstiegs-Bremsmitteln ausgestattete Lastkörper eines Artillerie-Trägerprojektiles ausgelegt, die nach Verschuß über ein zu verifizierendes Zielgebiet aus dem Trägerprojektil freigebbar sind. Das Relais ist mit einem Bremsmittel für wesentlich geringere Sinkgeschwindigkeit ausgestattet als der rotierend und dabei das Zielgebiet spiralförmig einengend abtastende Sensor.DE 41 04 800 C2 discloses a device for real-time terrain reconnaissance by means of at least one sensor, which is a load body from a carrier projectile according to Art a submunition is transferable and its information to a relay remote receiving station are transferable.
