Abstract
Description
l0 15 20 25 30 519 sçe Ändamålet med föreliggande uppfinning är att åstadkomma ett förfarande och ett skyddssystem som tillämpar samma princip för att sätta ett hot ur spel, nämligen att retroreflektera laserljuset mot hotet, men som inte är så begränsat i användningsområde och till exempel lämpar sig väl för användning både på land och till sjöss. The object of the present invention is to provide a method and a protection system which applies the same principle to put a threat out of play, namely to retrore tera the laser light against the threat, but which is not so limited in area of use and for example suitable well suited for use both on land and at sea.
Uppfinningsändamålet uppnås dels genom ett forfarande kännetecknat av att vid hot från laseranordning retroreflektorema kastas eller skjuts ut från skyddsföremålet eller angränsande område och dels genom ett skyddssystem kännetecknat av att en utkastnings- eller utskjutningsanordning är anordnad i anslutning till skyddsfóremålet för att genom utkastning eller utskjutning aktivera retroreflektorema.The object of the invention is achieved partly by a method characterized in that in the event of a threat from a laser device the retroreectors are thrown or pushed out of the protected object or adjacent area and partly by a protection system characterized in that an ejection or ejection device is arranged in connection with the protective object. .
Genom att frångå fasta reflektorer och istället kasta eller skjuta ut reflektorer när ett hot detekteras, ställs inga speciella krav på utformningen av skyddsföremålet. Själva utkastnings- eller utskj utningsanordningen kan antingen monteras i ett lämpligt utrymme på skyddsföremålet eller anordnas separat i dess närhet.By departing from fixed rejectors and instead throwing or firing rejectors when a threat is detected, no special requirements are placed on the design of the object of protection. The ejection or ejection device itself can either be mounted in a suitable space on the object of protection or arranged separately in its vicinity.
Utkastningen eller utskj utningen av retroreflektorema får till effekt att ett målinmätande system, där en hotlaseranordning ingår, får multipla ekon resulterande i att korrekt målinmätning försvåras eller fórdröjs. En annan effekt är att den hotande laseranordningen kan skadas genom att retroreflektorema returnerar en mycket kraftigare reflex än mottagaren är dimensionerad för, varvid denna skadas eller slås ut.The ejection or ejection of the retroreectors has the effect that a target measuring system, which includes a hot laser device, has multiple echoes resulting in correct target delay being delayed or delayed. Another effect is that the threatening laser device can be damaged by the retractors returning a much more powerful object than the receiver is dimensioned for, whereby this is damaged or knocked out.
I sammanhanget kan påpekas att det i och för sig är känt att kasta eller skjuta ut andra typer av reflektorer, se exempelvis vårt US patent 4 650 092. Det är i detta fall fråga om helt annan typ av reflektorer avsedda för radarfrekvenser. Reflektorema skall skapa ett reflekterande mål som avleder en fientlig radar från skyddsföremålet, vanligen ett flygplan. Det förs ingen diskussion om retroreflekterande reflektorer och inte heller om störande eller skadande inverkan på hotets mottagare.In this context, it can be pointed out that it is known per se to throw or launch other types of rejectors, see for example our US patent 4,650,092. In this case, it is a question of a completely different type of rejectors intended for radar frequencies. The reactors shall create a reflecting target that diverts an enemy radar from the object of protection, usually an eye plane. There is no discussion about retroactive actuators, nor about the disturbing or damaging effect on the recipient of the threat.
Enligt ett fördelaktigt utförande av förfarandet kastas eller skjuts retroreflektorema uti riktning mot den hotande laseranordningen. Alternativt kan retroreflektorema kastas 10 20 25 30 519 8663 eller skjutas ut i olika riktningar runt skyddsföremålet. Bl a typ av skyddsföremål och skyddsföremålets placering kan ligga till grund för val av förfarande.According to an advantageous embodiment of the method, the retroreectors are thrown or pushed in the direction of the threatening laser device. Alternatively, the retroreectors may be thrown or ejected in different directions around the object of protection. Among other things, the type of protective object and the location of the protected object can be the basis for choosing a procedure.
Enligt ett fördelaktigt skyddssystem är retroreflektorema anordnade i en utskj utbar bärare, såsom en proj ektil. Retroreflekrorema kan därvid under första delen av utskj utningsfasen skyddas av bäraren. Skyddssystemet medger även att det mål som retroreflektorerna skapar kan läggas på ett förhållandevis stort avstånd från skyddsföremålet om så önskas.According to an advantageous protection system, the retractors are arranged in a removable carrier, such as a projectile. The retrore squares can then be protected by the carrier during the first part of the launching phase. The protection system also allows the target created by the retroreectors to be placed at a relatively large distance from the object of protection if desired.
Genom att variera bärarens utformning, finns möjlighet att skapa större eller mindre spridning av retroreflektorema. Möjligt är att utforma bäraren så att retroreflektorema matas ut en efter en. Raka motsatsen är att alla retroreflektorema lämnar bäraren samtidigt. Skyddssystemet är kännetecknat av att den utskjutbara bärarens utformning är anordnad att styra retroreflektoremas spridningsförlopp.By varying the design of the carrier, it is possible to create a greater or lesser spread of the retroreectors. It is possible to design the carrier so that the retroreectors are output one by one. The exact opposite is that all retroreectors leave the wearer at the same time. The protection system is characterized in that the design of the extendable carrier is arranged to control the spreading process of the retroreectors.
Enligt ett annat fördelaktigt skyddssystem är retroreflektorerna utkastbart eller utskj utbart anordnade i en under retroreflektorernas utskjutning fixerad behållare.According to another advantageous protection system, the retroreectors are ejectionable or extendable arranged in a container axed during the firing of the retroreectors.
Enligt detta system kan snabbt uppnås stor spidning av retroreflektorerna i skyddsföremålets närhet. Spridningen kan med fördel ökas genom att aktivera flera behållare. En spridningsökning kan även åstadkommas vid tidigare berörda utföranden med utskjutbara bärare genom att aktivera flera bärare.According to this system, large spreading of the retroreectors in the vicinity of the protected object can be achieved quickly. The spread can advantageously be increased by activating several containers. An increase in spread can also be achieved in previously affected embodiments with extendable carriers by activating your carriers.
Uppfinningen kommer att beskrivas närmare nedan i exemplifierad form under hänvisning till bifogade ritningar, där: Figur l schematiskt visar ett exempel på ett stridsfält med skyddsföremål och hot.The invention will be described in more detail below in exemplary form with reference to the accompanying drawings, where: Figure 1 schematically shows an example of a battlefield with protected objects and threats.
Figer 2 schematiskt visar delar av i skyddssystemet enligt uppfinningen ingående utrustning.Fig. 2 schematically shows parts of equipment included in the protection system according to the invention.
Figur 3 visar ett schematiskt exempel på en utskj utbar bärare som kan ingå i skyddssystemet enligt uppfinningen. 10 15 20 25 30 519 8664 Figur 4 visar ett schcmatiskt exempel på en behållare med retroreflektorer som kan ingå i skyddssystemet enligt uppfinningen.Figure 3 shows a schematic example of a removable carrier which can be included in the protection system according to the invention. 10 15 20 25 30 519 8664 Figure 4 shows a schematic example of a container with retroreectors that can be included in the protection system according to the invention.
I det i figur 1 visade stridsfältct 1 befinner sig ett skyddsföremål i form av en stridsvagn 2 och ett hot i form av en stridsvagn 3 med en laseranordning 4. I det illustrerade läget är laseranordningen aktiv inom ett markerat område 5. På stridsvagnen 2 finns, se figur 2, en laservarnare 6 med laserljussensor 7 monterad.In the battlefield 1 shown in Figure 1, a protective object in the form of a tank 2 and a threat in the form of a tank 3 with a laser device 4. In the illustrated position, the laser device is active within a marked area 5. On the tank 2, see Figure 2, a laser detector 6 with laser light sensor 7 mounted.
Laservarnaren 6 är kopplad till en utskj utningsmekanism 8. När stridsvagnens 3 laseranordning 4 belyser stridsvagnen 2, mottager laserlj ussensom 7 strålning som laservamaren 6 uppfattar som ett hot. Laservamaren kan vara så utformad att en enda detekterad laserpuls räcker för att den skall uppfatta ett hot. Laservamaren skall också reagera på svag belysning och man bör därvid ta en viss integretiontid i beaktande.The laser warning 6 is connected to a firing mechanism 8. When the laser device 4 of the tank 3 illuminates the tank 2, the laser light sensor 7 receives radiation which the laser guard 6 perceives as a threat. The laser guard can be designed so that a single detected laser pulse is sufficient for it to perceive a threat. The laser guard should also react to dim lighting and a certain integration time should be taken into account.
Genom laservarnarens försorg aktiveras utskjutningsmekanismen 8 som kommer att skjuta ut retroreflektorer 9.By the action of the laser warning, the firing mechanism 8 is activated which will eject retroreectors 9.
I figuren 1 visas exempel på fyra retroreflektorer 9.1-9.4 som skjutits ut. Av dessa fyra retroreflektorer befinner sig tre retroreflektorer 9.1-9.3 inom det område 5 som laseranorningen 4 är aktiv, medan retroreflektorn 9.4 råkat hamna utanför området.Figure 1 shows examples of four retrore ectors 9.1-9.4 that have been extended. Of these four retrore ectors, three retrore ectors 9.1-9.3 are within the area 5 in which the laser device 4 is active, while the retrore ectector 9.4 has happened to fall outside the area.
Retroreflektorema 9.1-9.3 kommer att reflektera laserstrålningen tillbaka mot hotet 3.The retractors 9.1-9.3 will reflect the laser radiation back towards the threat 3.
Den reflekterade laserstrålningen förorsakar problem i stridsvagnens 3 utrustning.The reflected laser radiation causes problems in the tank 3's equipment.
Korrekt målinmätning försvåras eller fördröjs på grund av multipla ekon som uppträder i stridsvagnens målinmätande utrustning. Laseranordningen 4 riskerar dessutom att skadas eller slås ut av de oväntade och mycket kraftiga reflektionerna som retroreflektorerna 9 förorsakar.Correct target measurement is made more difficult or delayed due to multiple echoes appearing in the tank's target measuring equipment. The laser device 4 also risks being damaged or knocked out by the unexpected and very strong reactions caused by the retroreectors 9.
Figur 3 visar en utskj utbar bärare av retroreflektorer 9 i form av en projektil 10.Figure 3 shows a removable carrier of retroreectors 9 in the form of a projectile 10.
Projektilen 10 innefattar en i bakdelen anordnad kastladdning 11 för utkastning av retroreflektorerna 9. För drivning av proj ektilen finns drivladdning av konventionellt slag och beskrivs därför ej närmare. gur 4 visade utförandet retroreflektorerna 9 inrymda i en hylsa 12. En drivladdning 13 i botten av hylsan driver vid aktivering ut retroreflektorema 9 ur 519 8665 hylsan 12. Bl a drivladdningens styrka och hylsans 12 dimensioner kan varieras för att åstadkomma önskat spridningsmönster.The projectile 10 comprises a throw charge 11 arranged in the rear part for ejecting the retroreectors 9. For driving the projectile, there is a propellant charge of a conventional type and is therefore not described in more detail. Figure 4 shows the embodiment of the retroreectors 9 housed in a sleeve 12. When activated, a propellant charge 13 at the bottom of the sleeve drives the retroreectors 9 out of the sleeve 12. Among other things, the strength of the propellant charge and the dimensions of the sleeve 12 can be varied to achieve the desired scattering pattern.
Retroreflektorema kan utformas på många sätt. Ett exempel på retroreflektorer är kubhörnsprismor som kan vara utformade i glas eller luft. Ett annat exempel är kulor av företrädesvis glas. Det är även tänkbart att prägla retroreflektorer. Dessa exempel på retroreflektorer är bara några av många tänkbara exempel och skall inte på något sätt ses som begränsande för uppfinningen.The retroreectors can be designed in many ways. An example of retrore ectors is cube corner prisms that can be designed in glass or air. Another example is balls of preferably glass. It is also conceivable to characterize retrore flectors. These examples of retroreectors are just some of the many conceivable examples and should in no way be construed as limiting the invention.
