Description
Oppfinnelsen gjelder en fremgangsmåte til å formidle data som detekteres i et dyptflyvende objekt, særlig et oppklaringsfly, til en fjerntliggende markstasjon utrustet med en mottagerantenne. The invention relates to a method for transmitting data detected in a deep-flying object, in particular a reconnaissance aircraft, to a remote ground station equipped with a receiving antenna.
Ved direkte overforing av data fra det flyvende objekt til markstasjonen over radio støter man på vanskeligheter pga. ob-jektets lave flyvehøyde, da skyggevirkninger i terrenget kan av-bryte radioforbindelsen, og også de forutsetninger for utbredelse av bølger som bl.a. er gitt ved antennenes strålingskarakteri-stikker, er ugunstige nær jordoverflaten. Dessuten er denne form for dataoverføring meget lett å forstyrre. When transferring data directly from the flying object to the ground station via radio, difficulties are encountered due to the object's low flying height, as shadow effects in the terrain can interrupt the radio connection, and also the prerequisites for the propagation of waves such as are given by the antennas' radiation characteristics, are unfavorable near the earth's surface. Moreover, this form of data transmission is very easy to disrupt.
Vanskelighetene når det gjelder overføringsbetingelser blir mildnet hvis en satelitt eller et fly over eget terreng tjener som radio-reléstasjon mellom objektet som flyr i motstanderens område, og markstasjonen. The difficulties in terms of transmission conditions are mitigated if a satellite or an aircraft over its own terrain serves as a radio relay station between the object flying in the opponent's area and the ground station.
Men også denne radiooverføring lar seg forholdsvis lett forstyrre av støyapparatur hos motstanderen, og støysikkerhet lar seg ikke realisere. But even this radio transmission can be relatively easily disrupted by the opponent's noise equipment, and noise safety cannot be realized.
Tilsvarende gjelder for et data-overføringssystem som er kjent fra US-PS 3.092.770, og hvor to deltagere kommuniserer via en transponder som utskytes med rakett og holdes luftbåren ved hjelp av en fallskjerm for langdistanse-dataoverføring. The same applies to a data transmission system which is known from US-PS 3,092,770, and where two participants communicate via a transponder that is launched with a rocket and kept airborne by means of a parachute for long-distance data transmission.
Oppfinnelsens oppgave er å gi anvisning på en fremgangsmåte som praktisk talt ikke lar seg forstyrre, til overføring av data fra et dyptflyvende objekt til en fjerntliggende markstasjon. Ifølge oppfinnelsen blir denne oppgave løst ved at vedkommende data innføres i et lager anbragt i et flyvelegeme, f.eks. en rakett, som føres med av det flyvende objekt, at flyvelegemet med det i det minste delvis fylte lager skytes ut fra det flyvende objekt i retning mot markstasjonen og så gjennomløper en høy, i det vesentlige ballistisk flyvebane, og at de lagrede data etter at markstasjonens mottagningsområde er nådd, blir sendt ut ved hjelp av en radiosender i flyvelegemet for mottagning ved hjelp av markstasjonen. The task of the invention is to provide instructions for a method that practically cannot be disturbed, for the transmission of data from a deep-flying object to a remote ground station. According to the invention, this task is solved by the relevant data being entered into a storage placed in an aircraft body, e.g. a rocket, which is carried along by the flying object, that the flight body with the at least partially filled storage is launched from the flying object in the direction of the ground station and then traverses a high, essentially ballistic flight path, and that the stored data after the ground station's reception area is reached, is sent out using a radio transmitter in the fuselage for reception by the ground station.
Oppfinnelsen vil i det følgende bli belyst under henvisning til tegningen. The invention will be explained below with reference to the drawing.
Over et fiendtlig oppklaringsområde 1 flyr i liten høyde, f.eks. 300 meter, et eget oppklaringsf ly 2. I det egne område 3 befinner der seg en mark- og tydningsstasjon 4 med en mottagerantenne. Fra forst av er der på flyet 2 under oppklaringen anbragt et flyvelegeme 5, f.eks. en rakett, som fores med av flyet 2. Med flyet 2 blir f.eks. overlappende bilder eller også ønskede enkeltinformasjoner om det overfløyede fiendtlige område 1 tatt opp og i form av data innfort i et lager anbragt i flyvelegemet 5. Når lageret i det minste delvis er fylt med data, blir flyvelegemet 5 skutt ut av flyet 2 i retning mot markstasjonen 4 og gjennomløper en høy, i det vesentlige ballistisk fluktbane 6. Etter at mottagningsområdet for den egne markstasjon 4 er nådd, skjer etter det såkalte akvisisjonsområde 7 utsendelse av de lagrede data fra flyvelegemet 5, så disse mottas ved hjelp av antennen i markstasjonen 4 og deretter tydes. For å oppnå en større reserve av støysikkerhet kan man gjøre bruk av den vanlige Spread-spectrum-metode. Under utførelsen av flyets oppklarings-oppdrag er flyet 2 og flyvelegemet 5 uvirksomme med hensyn til sending. Flyvelegemet 5 påbegynner først datasendeprosessen i akvisisjonsområdet 7. Det er nok å anvende en enkel sender med liten sendereffekt i flyvelegemet 5, så tapet av en slik sender ikke blir særlig kostbart. I markstasjonen 4 behøves heller ikke særlig kostbart utstyr til mottagningen av data. Utføres antenne-utstyret i markstasjonen 4 imidlertid mer avansert, f.eks. med en spesiell antennestrålingskarakteristikk eller en antenne-kølle-etterføring, kan også støysikkerheten økes. Støysikkerheten ved dataoverføringsmetoden ifølge oppfinnelsen er i det vesentlige avhengig av skyggevirkninger fra terrenget og av passitiviteten av markstasjonen 4. Selve markstasjonen 4 kan være utført mobil. Det er også mulig å gjennomføre en Diversity-drift med flere markstasjoner. Også en drift i motstanderens radarbånd er mulig. Over an enemy reconnaissance area 1 flies at low altitude, e.g. 300 metres, a separate reconnaissance aircraft 2. In the separate area 3 there is a ground and interpretation station 4 with a receiver antenna. From the outset, an aircraft body 5, e.g. a rocket, which is carried by plane 2. With plane 2, e.g. overlapping images or also desired individual information about the enemy area 1 flown over are recorded and in the form of data entered into a warehouse located in the aircraft body 5. When the warehouse is at least partially filled with data, the aircraft body 5 is launched from the aircraft 2 in the direction of the ground station 4 and traverses a high, essentially ballistic flight path 6. After the reception area for the own ground station 4 has been reached, the so-called acquisition area 7 sends out the stored data from the flight body 5, so that these are received with the help of the antenna in the ground station 4 and then decipher. In order to achieve a greater margin of noise safety, the usual spread-spectrum method can be used. During the execution of the aircraft's reconnaissance mission, the aircraft 2 and the fuselage 5 are inactive with respect to transmission. The airframe 5 first begins the data transmission process in the acquisition area 7. It is sufficient to use a simple transmitter with a small transmitter power in the airframe 5, so that the loss of such a transmitter is not particularly costly. In field station 4, particularly expensive equipment is not required for the reception of data either. However, if the antenna equipment in ground station 4 is more advanced, e.g. with a special antenna radiation characteristic or an antenna-club follow-up, the noise safety can also be increased. The noise safety of the data transmission method according to the invention is essentially dependent on shadowing effects from the terrain and on the passivity of the field station 4. The field station 4 itself can be made mobile. It is also possible to carry out a Diversity operation with several field stations. A drift in the opponent's radar band is also possible.
Som lagre i flyvelegemene 5 kan man f.eks. anvende magnet-båndlagre, magnetplatelagre, optiske lagre, f.eks. i form av et filmlager, eller for mindre datamengder, halvlederlagre. As bearings in the airframes 5, one can e.g. use magnetic tape storage, magnetic disk storage, optical storage, e.g. in the form of a film storage, or for smaller amounts of data, semiconductor storage.
Ved billedopptaket i det flyvende objekt 2 kan der f.eks. anvendes et billedlagerrør. Avsøkningen av.bildet blir da uavhen-gig av billedopptaket. Korte belysningstider lar seg oppnå, og slettelsen av bildet kan velges fritt. During the image recording in the flying object 2, there can e.g. an image storage tube is used. The scanning of the image is then independent of the image recording. Short exposure times can be achieved, and the deletion of the image can be freely selected.
