Description

Radarsichtgerät Zusatz zum Patent: 1 216 555 Im Hauptpatent 1 216 555 ist ein Radarsichtgerät mit einer Bildröhre zur Anzeige der Reflexion impulse in einer von der Bildschirmmitte ausgehenden Panoramadarstellung vorgeschlagen worden, bei dem eine selektive Beeinflussung der Helligkeit der Festzielanzeigen dadurch erfolgt, daß zur Vergleichmäßigung der Helligkeit der Festziele in an sich bekannter Weise vor dem Bildschirm ein Filter angeordnet ist, das im Spektralbereich des Bildschirmlichtes eine vom Rand zur Mitte wachsende Absorptionsfähigkeit hat, und daß zur Hervorhebung wichtiger Festziele das Filter an den betreffenden Stellen transparent ist.Radar viewer Addendum to patent: 1 216 555 in main patent 1 216 555 is a radar display device with a picture tube to display the reflection impulses has been suggested in a panorama view starting from the center of the screen, in which a selective influencing of the brightness of the fixed target displays thereby takes place that to equalize the brightness of the fixed targets in per se known Way in front of the screen a filter is arranged in the spectral range of the screen light has an absorbency increasing from the edge to the center, and that for emphasis important fixed goals the filter is transparent at the relevant points.

Diese Anordnung hat sich zur Vermeidung von für die Beobachtung lästigen Überstrahlungen der Radarschirmbilder bewährt; sie ist jedoch nur dann optimal, wenn das Zentrum des Schirmbildes in der Bildschirmmitte liegt. Wenn letzteres nicht der Fall ist, wird in Weiterbildung der Anordnung nach dem Hauptpatent das Filter so ausgebildet, daß es eine zum Bildschirmmittelpunkt dezentriert liegende Absorptionsverteilung entsprechend dem dezentrierten Radarbild hat. This arrangement has been found to avoid the nuisance of observation Tried and tested overexposure to radar screens; however, it is only optimal when the center of the screen is in the middle of the screen. If the latter is not is the case, in a further development of the arrangement according to the main patent, the filter designed so that there is an absorption distribution that is decentered from the center of the screen according to the decentered radar image.

Die Zeichnung stellt ein Ausführungsbeispiel schematisch dar. The drawing shows an exemplary embodiment schematically.

F i g. 1 zeigt einen Querschnitt und F i g. 2 eine Draufsicht. F i g. 1 shows a cross section and FIG. 2 is a plan view.

Die zum Zwecke der Herstellung der gewünschten dezentrierten Absorptionsverteilung übereinanderliegenden Folien, deren Dicke der Deutlichkeit halber stark übertrieben gezeichnet wurde, sind mit 1 bis 4 bezeichnet. Die Folien, die auf dem Schirm 5 des Radarsichtgerätes liegen, können jeweils die gleiche Absorption haben oder auch in ihrer Absorption voneinander abweichen. Die Helligkeit der Festziele wird dadurch festgelegt, daß z. B. Aussparungen 6 und 7, die durch Wegätzen oder Ausschneiden hergestellt werden, nur in einigen Folien vorgesehen werden, wobei die Ränder aller Aussparungen den Konturen der entsprechenden Festziele angepaßt oder die Aussparungen einer jeden Folie in ihrem Umfang von Folie zu Folie kleiner sind, wie in der F i g. 1 angedeutet. Die übereinanderliegenden Folien können zwar alle vom gleichen Umfang sein, jedoch größere oder kleinere Absorptionsflächen 1' bis 3' besitzen, so daß ihre Lage zum Schirm 5 bzw. Schirm 5' unverändert bleibt, die Absorptionswirkung aber jeweils der Dezentrierung des Schirmbildes angepaßt werden kann. The one for the purpose of producing the desired decentered absorption distribution overlapping foils, the thickness of which is greatly exaggerated for the sake of clarity are marked with 1 to 4. The foils that are on the screen 5 of the radar display device can each have the same absorption or else differ in their absorption. The brightness of the fixed targets is thereby stipulated that z. B. recesses 6 and 7, which by etching or cutting out can only be provided in some foils, with the edges of all Recesses adapted to the contours of the corresponding fixed targets or the recesses of each film are smaller in their circumference from film to film, as in F i g. 1 indicated. The overlapping foils can all be the same Be circumference, but have larger or smaller absorption areas 1 'to 3', so that their position relative to the screen 5 or screen 5 'remains unchanged, the absorption effect but can be adapted to the decentering of the screen image.

Wie aus Fig. 2 ersichtlich, wird die Absorption nicht zentral vom mechanischen Mittelpunkt des Schirmbildes aus geändert, sondern entsprechend einem dezentrierten Radarbild, bei dem der Standort des Radargerätes immer der elektrische Mittelpunkt ist, angepaßt. As can be seen from Fig. 2, the absorption is not centrally from mechanical center of the screen changed, but according to a decentered radar image in which the location of the radar device is always the electrical one Center is adjusted.

Bei feststehendem Standort des Radargerätes und im allgemeinen über längere Zeit anwesenden Festzielen, wie z. B. bei einem Flugplatz, können die Absorptionsflächen verschiedener Durchlässigkeit oder eine Folie entsprechend verlaufender Absorption auch durch Einfärben hergestellt werden, wobei die den Festzielen entsprechenden Flächen dann weniger gefärbt werden, d. h. eine größere Transparenz haben. With a fixed location of the radar device and generally over Fixed targets that are present for a longer period of time, such as B. at an airport, the absorption surfaces different permeability or a film with corresponding absorption can also be produced by coloring, with those corresponding to the fixed objectives Areas are then less colored, i.e. H. have greater transparency.
