Description
15 20 25 30 35 532 'IÜÛ målinflygningen. På det sättet öppnar man en möjlighet för motståndaren att inleda försvarsåtgärder mot platsen för laser-designatorn. Även om ett sådant sökhuvud kan drivas i tre olika moder, nämligen som semi-aktiv sistapulslogik ("last-pulse-logic") - sökare, som infrarödsökare eller som laser-infraröd- korrelerad sökare har sådana sökhuvud som följd av de tidigare nämnda nackdelarna inte slagit igenom i praktiken. 15 20 25 30 35 532 'IÜÛ the target approach. In this way, an opportunity is opened for the opponent to initiate defensive measures against the position of the laser designer. Although such a search head can be operated in three different modes, namely as a semi-active last-pulse logic ("last-pulse-logic") viewfinder, as an infrared viewfinder or as a laser-infrared-correlated viewfinder, such search heads have due to the aforementioned disadvantages. not broken through in practice.
Här börjar uppfinningen nu, vars uppgift det är att skapa ett nytt dual-mod-huvud vilket är bättre lämpat för användning i samband med självdrivna styrflygkroppar.Here begins the invention now, the task of which is to create a new dual-mode head which is better suited for use in connection with self-propelled fuselages.
Denna uppgift löses uppfinningsenligt genom särdragen i patentkrav 1.This object is solved according to the invention by the features of claim 1.
Ytterligare särdrag för uppfinningen följer ur de osjälvständiga kraven.Additional features of the invention follow from the dependent claims.
Uppfinningen möjliggör drivning av en laserpunktsensor för att upptäcka och identifiera ett lasermarkerat mål och för att driva en okyld bildgivande infrarödsensor för autonom målföljning under slutinflygningen genom bestämning av träffpunkten på målet via ett gemensamt bispektralt objektiv. Härvid använder man en spektral stràldelningsspegel och en relayoptik i lasersensorkanalen genom vilken laserpunktsensorns bildfält kan väljas i huvudsak oberoende av infrarödsensorns bildfält och under kontroll av den optiska aberrationen. Manövreringssignalerna skapas beroende av sensorsignalerna genom en signalbehandlingselektronik och där det via slgnalbehandlingselektroniken sker en operationell process för mällåsning och förföljning efter avfyrande av flygkroppen.The invention enables the operation of a laser point sensor to detect and identify a laser-marked target and to operate an unchilled imaging infrared sensor for autonomous target tracking during the final approach by determining the point of impact on the target via a common bispectral lens. A spectral beam splitting mirror and a relay optics in the laser sensor channel are used, through which the image field of the laser point sensor can be selected substantially independently of the image field of the infrared sensor and under the control of the optical aberration. The operating signals are created depending on the sensor signals through a signal processing electronics and where an operational process for target locking and tracking after firing of the fuselage takes place via the signal processing electronics.
Den uppfinningsenliga utformningen av dual-mode-sökhuvudet är särskilt fördelaktig eftersom man till skillnad från ett sökhuvud med enbart en laserpunktsensor genom infrarödsensorn erhåller en reducering av tiden för den aktiva målbelysningen ner till ett minimum, nämligen ner till mållåsningen av den som målsökare arbetande infrarödsensorn. Ett sökhuvud med enbart en bildgivande infrarödsensor skulle däremot för att kunna uppnå de operationellt nödvändiga upptäcknings- och identifieringsräckvidderna behöva tillverkas med betydligt mer komplicerad teknologi, nämligen med kylda MCT- eller lnSb-sensorer. För målspàrning skulle man behöva täcka ett mycket större synfält och för identifiering skulle man behöva realisera en hög geometrisk upplösning. Detta kräver en dyr sensor med ett stort antal pixlar. 10 15 20 25 30 532 'IÛO Fördelen med uppfinningen ligger därmed i synnerhet i att uppgifterna spårning och identifiering av målet kan tilldelas laserkanalen där de kan utföras av en enkel detektor med en 4-kvadrants-fotodiod. Eftersom den geometriska upplösningen för denna sorts detektor är låg utanför bildens mitt kan man lätt realisera en passande optik vilken överför ett för detektering fördelaktigt stort bildfält.The design of the dual-mode search head according to the invention is particularly advantageous because, unlike a search head with only one laser point sensor through the infrared sensor, a reduction of the time for the active target lighting is obtained down to a minimum, namely down to the target locking of the infrared sensor. On the other hand, a search head with only an imaging infrared sensor would need to be manufactured with much more complicated technology, namely with cooled MCT or lnSb sensors, in order to be able to achieve the operationally necessary detection and identification ranges. For target tracking, a much larger field of view would need to be covered, and for identification, a high geometric resolution would need to be realized. This requires an expensive sensor with a large number of pixels. The advantage of the invention thus lies in particular in the fact that the tasks of tracking and identifying the target can be assigned to the laser channel where they can be performed by a simple detector with a 4-quadrant photodiode. Since the geometric resolution of this type of detector is low outside the center of the image, a suitable optics can easily be realized which transmits a large image field advantageous for detection.
Därefter styr lasersensorn visirlinjen så att det identifierade målet är centrerat i synfåltet för de båda mot varandra riktade sensorerna. Därefter tar en passiv målsökare som är kopplad efter infrarödsensorn över màlkonturen i sensorns mitt, så att den aktiva mälbelysningen kan stängas av. Till denna uppgift behöver den infraröda bildsensorn enbart ett litet synfält. Den infraröda bildsensorns termiska och geometriska upplösning är tillräcklig för att möjliggöra en tracker-låsning. Detta kräver dock betydligt mindre av sensorn och den tillhörande bildbehandlingen än en identifiering med samma avstånd till målet.Thereafter, the laser sensor controls the visor line so that the identified target is centered in the field of view of the two sensors facing each other. Then a passive target finder connected to the infrared sensor takes over the target contour in the middle of the sensor, so that the active target light can be switched off. For this task, the infrared image sensor only needs a small field of view. The thermal and geometric resolution of the infrared image sensor is sufficient to enable tracker locking. However, this requires significantly less of the sensor and the associated image processing than an identification with the same distance to the target.
Den ”enögda” uppbyggnaden med det gemensamt utnyttjade bispektrala objektivet möjliggör en särskilt fördelaktig kompakt anordning med enkelt realiserbar harmonisering av de optiska axlarna och är dessutom kostnadseffektiv. l regel använder man reflektiv optik för bispektrala avbildningar om de spektrala områden som skall avbildas ligger långt ifrån varandra (jfr till exempel US 7 049 597). Med sådan optik är det dock mycket svårt att uppnå de nödvändiga små öppningstalen i bägge sensorkanaler och en storlek på synfältet kring 10° i laserkanalen. Med de refraktiva optiska material som finns tillgängliga (ZnS, ZnSe, BaFZ) kan man däremot mycket väl realisera bispektral optik vilken uppfyller ovannämnda kriterier.The "one-eyed" construction with the commonly used bispectral lens enables a particularly advantageous compact device with easily realizable harmonization of the optical axes and is also cost-effective. As a rule, reflective optics are used for bispectral images if the spectral areas to be imaged are far apart (cf., for example, US 7,049,597). With such optics, however, it is very difficult to achieve the necessary small aperture numbers in both sensor channels and a size of the field of view around 10 ° in the laser channel. With the refractive optical materials available (ZnS, ZnSe, BaFZ), however, one can very well realize bispectral optics which meet the above criteria.
Slutligen kan man också utrusta laserkanalen med en aktiv laseravståndsmätare vilket ytterligare möjliggör en användning av en integrerad avstàndständare. l stridsinsatser år det i synnerhet fördelaktigt att bestämningen av laserdesignatorns läge och inledande av motåtgärder blir svårare, om inte omöjliga att genomföra.Finally, the laser channel can also be equipped with an active laser rangefinder, which further enables the use of an integrated rangefinder. In combat operations, it is particularly advantageous that the determination of the position of the laser designer and the initiation of countermeasures become more difficult, if not impossible, to carry out.
Förutom det beskrivna dual-mod-driftläget vid vilket bägge sensorer sekventiellt generar insignalerna, vilka används för orientering och efterföljning av visirlinjen med avseende pà målet, är naturligtvis också de enkla driftlägena möjliga: styrning genom enbart lasersensorn vid permanent målbelysning fram till träffen eller rent passiv bekämpning 10 15 20 25 30 53.? '100 genom att en användare markerar målet i infrarödsensorns bild och därmed kopplar in en màlsökare.In addition to the described dual-mode operating mode in which both sensors sequentially generate the inputs, which are used for orientation and tracking of the visor line with respect to the target, the simple operating modes are of course also possible: control by the laser sensor only in permanent target lighting until the hit or purely passive control 10 15 20 25 30 53.? '100 by a user selecting the target in the image of the infrared sensor and thereby engaging a target finder.
Uppfinningen kommer i fortsättningen beskrivas med hjälp av ett i ritningen mer eller mindre schematiskt framställt utföringsexempel.The invention will be described in the following by means of an exemplary embodiment more or less schematically represented in the drawing.
Det visas i Figur 1 en framställning av en flygkroppslancering under målflygningen, figur 2 ett snitt genom ett dual-mod-sökhuvud enligt uppfinningen, figur 3 uppbyggnadsprincipen för dual-mod-sökhuvudet enligt figur 2, figur 4 en schematisk framställning av bildfältet för dual-mod-sökhuvudets sensorers enligt figur 2 och figur 5 ett kretsschema för signalbehandlingselektroniken.Figure 1 shows a representation of a fuselage launch during the target flight, Figure 2 is a section through a dual-mode search header according to the invention, Figure 3 shows the construction principle of the dual-mode search header according to Figure 2, Figure 4 shows a schematic representation of the image field for dual-mode search heads. the sensors of the mode search head according to Figure 2 and Figure 5 are a circuit diagram of the signal processing electronics.
En möjlig flygbana av en styrflygkropp bärandes ett duaLmOd-sökhuvud innefattar så som det visas i figur 1 till exempel en genom intertialnavigering styrd inflygningsbana A och en enligt proportionalnavigationsprincipen arbetande sökhuvudstyrda slutfas-flygbanan E, tills flygbanan träffar målet Z. Lasersensorn upptäcker och identifierar målet och centrerar det i synfältet genom visirlinjens styrning, vilken orienteras ungefär med hjälp av en tvàaxlig gimbals, på vilken en dual-mod-sensor finns monterad. Därefter kopplar infraröd- bildsensorn om till infraröd-màlkonturen i bildens mitt. Därefter sker övergången fràn den inertialt styrda flygbanan till den sökhuvudstyrda flygbanan. Slutfasstyrningen sker av sig självt enbart genom infrarödsensorn, vilket gör att belysning av målet genom en laserdesignator blir öveiflödig.A possible flight path of a control fuselage carrying a duaLmOd search head includes, as shown in Figure 1, for example an approach navigation controlled by intertial navigation and a search phase controlled final phase flight path E operating according to the principle of proportional navigation, until the flight path hits the target Z. centers it in the field of view by the control of the visor line, which is oriented approximately by means of a biaxial gimbals, on which a dual-mode sensor is mounted. Then the infrared image sensor switches to the infrared target contour in the center of the image. Then the transition takes place from the inertially controlled flight path to the search main controlled flight path. The final phase control takes place by itself only through the infrared sensor, which means that illumination of the target by a laser designer becomes superfluous.
Härvid innefattar det sammantaget med referensnummer 10 betecknade dual-mod- huvudet, så som det visas i figurerna 2 och 3, en 4-kvadrantdetektor 12, en relayoptik 13, en spektral stràldelare 14 och en infrarödsensor 16, vilken är tilldelad ett gemensamt objektiv 18. 4-kvadrantdetektorn 12 är utformad som lnGaAs-diodkombination och arbetar 10 15 20 25 30 35 532 'IOO i våglängdsintervallet från 1.06 till 1.55 pm motsvarande våglängden för den till målmarkering använda lasern.In this case, the dual-mode head, collectively designated by reference numeral 10, as shown in Figures 2 and 3, comprises a 4-quadrant detector 12, a relay optics 13, a spectral beam splitter 14 and an infrared sensor 16, which is assigned a common lens 18. The 4-quadrant detector 12 is designed as a lnGaAs diode combination and operates in the wavelength range from 1.06 to 1.55 μm corresponding to the wavelength of the laser used for target marking.
Som infrarödsensor används en bildgivande mikrobolometersensori form av en okyld detektorarray med 160 X 120 pixlar (focal-plane-array typ UL 02 051, från företaget Ulis, Grenoble), vilken är försedd med en spektral stràldelare 14 som träffas av infrarödandelen av strålningen genom objektivet 18 i dual-mod-sökhuvudet.The infrared sensor used is an imaging microbolometer sensor in the form of an uncooled detector array with 160 X 120 pixels (focal-plane array type UL 02 051, from the company Ulis, Grenoble), which is provided with a spectral beam splitter 14 which is struck by the infrared part of the radiation through the lens 18 in the dual-mode search header.
Relayoptiken 13 används för förstoring av detektorns 12 bildfält, vars yta är mindre än sensorns 16 yta, vilket visas i figur 4. Relayoptiken 13 förkortar därmed den sammanlagda brännvidden för ”laserkanalen” gentemot objektivets 18 brännvidd.The relay optics 13 are used to enlarge the image field of the detector 12, the area of which is smaller than the area of the sensor 16, as shown in Figure 4. The relay optics 13 thus shortens the total focal length of the "laser channel" relative to the focal length of the lens 18.
Dual-mod-sökhuvudet 10 innefattar vidare häri inte visade och i sig kända medel för styrning av dess visirlinje 15.The dual-mode search head 10 further includes means not shown herein and known per se for controlling its visor line 15.
Signalbehandlingen av det tidigare beskrivna dual-mod-sökhuvudet visas i figur 5 och är uppdelad i en analog signalförberedning med 4-kvadrant-detektorn 12 och dess digitala signalbehandling genom signalbehandlingselektroniken 20. Hos den använda lnGaAs- detektorn är katoderna sammanförda i en stjärnpunkt till skillnad från de vanligtvis använda ßt-kvadrant-detektornerna i germanium och klsel, vid vilka anoderna bildar en stjärnpunkt. På grund av den valda konfigurationen drivs Ll-kvadrant-detektorn 12 i fotovoltaikläget. Beroende på den infallande strålningen flyter en ström genom detektordioderna A1 till A4. De efterkopplade förstärkarna V1 till V4 har två uppgifter: För det första en impedansmätning och för det andra en förstärkning av signalnivåerna.The signal processing of the previously described dual-mode search header is shown in Figure 5 and is divided into an analog signal preparation with the 4-quadrant detector 12 and its digital signal processing by the signal processing electronics 20. In the lnGaAs detector used, the cathodes are combined in one star point in contrast. from the commonly used ßt quadrant detectors in germanium and klsel, at which the anodes form a star point. Due to the selected configuration, the L1 quadrant detector 12 is operated in the photovoltaic mode. Depending on the incident radiation, a current flows through the detector diodes A1 to A4. The connected amplifiers V1 to V4 have two tasks: firstly an impedance measurement and secondly an amplification of the signal levels.
Förstärkarnas utgångar leds var och en till en A/D-omvandlare W1 till W4. Deras utgångssignaler utvärderas därefteri en digital signalbehandlare 20 som också tillförs infrarödsensorns 16 signaler.The outputs of the amplifiers are each routed to an A / D converter W1 to W4. Their output signals are then evaluated in a digital signal processor 20 which is also applied to the signals of the infrared sensor 16.
Det ovan beskrivna dual-mode-sökhuvudet med sin bispektrala optik är kännetecknat genom en kompakt och utrymmessnàl uppbyggnad och samtidigt genom hög sökprestanda så att sökhuvudet också vid kardanlagring intar ett inbyggnadsutrymme av 70 mm i diameter och ungefär 100 mm i inbyggnadslängd, dvs. som är i hög grad lämpat för inbyggnad för styrflygkroppar fràn och med kalibern 75 mm. Inkoppling av infraröd- sökläget sker ungefär vid 2 km till 1,5 km avstånd till målet. 10 15 20 25 532 100 REFERENSNUMMERLISTA 12 4-kvadrantdetektor 13 relaisoptik 14 stràldelare 15 visirlinje 16 infrarödsensor 18 gemensamt objektiv 20 signalbehandlingselektronik A A1 till A4 E V1 till V4 W1 ti!!
