surakshit radar

spectrally agail frequency-incrementing reconfigurable (sephire) radar ack vaahan-mounted, forward-looking ground-penetrating radar (aff. ell. jee. pee. aar.) system haye jise dafan yaa chhipe hue visfotak khatron kaa pataa lagaane key liye design kiya gayaa haye. ise yuu dwara vikasit kiya gayaa thaa.aiss. 2016 mein senaa kii anusandhaan prayogshala (arl) ney ultra-wideband (udblueby) aur synthetic aperture radar (saar) pranaliyon kii ack lambi peedhi key hisse key roop mein dabi hui barudi surangon aur ied kaa mukabala karane key liye banaaya. pichhale punaraavrittiyon mein railsar, boomer aur saair radar shamil hain.
vikas.
sephire radar kii kalpana shuru mein wireless praudyogiki key halia vikas key kaaran radio aavritti (aar. aff.) spectrum kii badhati bheed key jawab key roop mein kii gaee thee. maujooda surr radar pranali mein sudhaar key prayaas key hisse key roop mein, yuu.aiss. senaa kii anusandhaan prayogshala ney sephire radar koo ack udblueby radar key roop mein design kiya haye joe bheedbhaad vaale rf vatavaran mein kaam karate hue saain radar key pradarshan seey mell khaa sakata haye yaa usase adhik hoe sakata haye. aaveg udblueby key bajaay, ise nyuntam adc namuna aavashyaktaon koo banaae rakhate hue varnakramiya chapalata banaae rakhane key liye ack charanbaddh-aavritti design key saath fitt kiya gayaa thaa. ack prayogaatmak radar key roop mein apani prakriti key kaaran sephire radar koo atyadhik punarsanyojit karane key liye bhee design kiya gayaa thaa.
sephire radar boomer aur saair radar jaise arl dwara vikasit pichhale udblueby saar system seey alag haye kyonki yeh ack short-puls key bajaay ack step-frequency system kaa upayog kartaa haye. ack aaveg udblueby pranali key roop mein saair radar kii prakriti key kaaran honey vaali mukhya chunautiyon mein seey ack inn-baind radio aavritti hastakshep (rfi) key liye isaki uchch samvedansheelta thee. isake vipareet, step-frequency radar apane operating baind key bheetar vishisht aavrittiyon koo utpaadit curr sakate hain, joe paas key radar system seey hastakshep koo cumm kartaa haye. isake alawa, aavritti baind jahaan aar. aff. aaee. maujood haye, unhein varnakramiya samvedan takneekon key upayog seey aasaani seey hataaya jaa sakata haye. isake alawa, jabaki aaveg udblueby radar jaise kii surr radar koo kuchh aarakshit aavritti baind mein sanketon koo sanchaarit karane seey bachana chaahiye, step-aavritti radar mein sanketon koo sanchaarit karane key liye lachilaapan hotaa haye joe kissy bhee varnakramiya aakar key anuroop hotey hain, jaba taka kii vaapsee sanketon koo shore koo cumm karane key liye sansaadhit kiya jaataa haye. iss drishtikon key parinamswarup radar imagery mein operating bandwidth parr aavrittiyon key baind hoe sakate hain, jisake parinamswarup koee detta naheen haye.
inn vinyason key kaaran, suraksha radar uchch aar. aff. samagri key saath bheedbhaad vaale varnakramiya kshetron seey bachane key saath tulaniya renz resolution aur pravesh kshamataon key saath ultra-wideband sanchaalan karane mein saksham haye. ack baar vikas puuraa honey key baad, safayar radar koo baad mein 2016 aur 2017 mein ack shushk senaa pareekshan sthal parr feeled parikshanon kii ack shrinkhala key adheen kiya gayaa thaa, jahaan ise poore sthal parr chhipi kaee tank-rodhi barudi surangon kaa pataa lagaane aur vibhinn gaharaai mein dafanaane kaa kaam saunpa gayaa thaa. inn prayogon key parinamon key anusaar, suraksha radar koo mitty mein 8 inch taka gahari dafan chaudi or unmukh bhoo-mines kaa pataa lagaane aur unaki chhavi banaane mein saksham dikhaaya gayaa thaa.
visheshataaen.
sephire radar 300 megahertz seey laker 2 gigahertz taka kii bandwidth parr sanchaalit hotaa haye, jisamen nyuntam aavritti charan aakar 1 megahertz hotaa haye. haalaanki, aavritti charan kaa aakar upayogkarta dwara nirdhaarit kiya jaa sakata haye aur aam taur parr vaahan kii gati dwara niyantrit kiya jaataa haye jiss parr pranali sthaapit kii jaati haye. jabaki bandwidth mein vriddhi seey resolution aur signal-too-clutter anupaat mein sudhaar hoe sakata haye, sephire key radar resolution koo vishesh roop seey ack vishisht anty-personnel (appy) landmine key aayamon key saath tulaniya honey key liye chunaa gayaa thaa. radar pranali radar operating baind key bheetar praapt sanket seey aar. aff. aaee. koo aur alag rakhane key liye ack superheterodine vastukala kaa upayog karati haye. ise atyadhik punarnirdhaarit samay niyantran key liye bhee design kiya gayaa thaa, jahan upayogkarta 8.33 nanosecond resolution key saath sanchaarit aur praapt karane key samay kaa chayan curr sakata haye.
antena.
sephire receiver antena koo ack samaan raikhik sarani mein vyavasthit kiya jaataa haye jisamen 16 aarl-nirmit vivaldi notch antena hotey hain. dou badey ee. tii.-lindgen kwad-grid horn transmit antena sarani key oopar tainaat hain aur radar avashoshit phome dwara praapt antena seey alag kiye jaate hain. radar pranali koo yaa tou aage yaa buggle mein dekhane vaale abhivinyas key liye configure kiya jaa sakata haye, lekin aisaa karane key liye vivaldi notch antena koo bhautik roop seey ghumaane kii aavashyakta hoti haye. isake vipareet, ee. tii. aiss.-lindgen horn antena koo urdhvaadhar yaa kshaitij dhruvikaran key beach electronic roop seey badala jaa sakata haye. iss vinyas key madhyam seey, suraksha pranali key liye poori tarah seey dhruviya aankada ekatra karna sambhav hoe jaataa haye.

praaptakarta.
receiver pahale mishran charan key dauran ack stepped lokal-ausilator (low) kaa upayog karke vartamaan sanchaalan aavritti koo track kartaa haye, joe stepped operating aavritti key liye ack sthir offset parr aayojit kiya jaataa haye. yeh pahala mishran charan 1700-megahertz operating bandwidth koo ack sankeern baind mein dhwast karane kaa kaam kartaa haye, jise phir pravardhit aur filter kiya jaataa haye. ack baar pravardhit honey key baad, sanketon koo chaar tarikon seey vibhajit kiya jaataa haye aur ack rx module seey jodaa jaataa haye, jisamen teen pee. see. bee. aiss. aur chaar receiver channel hotey hain.
cameray.
sephire radar mein dou electro-optical (eo) point gray pissu 2jee hd cameray aur dou lambi-tarang avarakt (lvr) zenix gobi 640 cameray bhee hain. eo cameray 2448x2048 resolution aur 7.5 frame prati sekand mein saksham hain, jabaki lweer cameray 55-emke samvedansheelta key saath 8 aur 14 micrometer key beach kaam karate hain. inn chaar camers seey utpann detta koo ekatra kiye gaye radar detta key saath upayogkarta key liye ack stereoscopic samvardhit vaastaviktaa pradarshan kaa utpaadan karane key liye adhiropit kiya jaa sakata haye joe unhein sabhi samvedak detta koo ack saath dekhane kii anumati detaa haye. isake alawa, yeh detta suraksha pranali key liye maujood vastuon kii sthaanik seema aur nikatata key baare mein jaankaari key saath drishya kaa metrick punarnirmaan utpann karna sambhav banaata haye. upayogkarta key dekhane key anubhav koo badhaane key liye gaharaai, rung, taapiya aur radar jaankaari key saath paryaavaran key 3dee metrick scan banaane key liye eo aur lvr camers seey detta koo sanyojit karane kii bhee yojana banaai gaee thee.
sthiti aur gati samvedak.
ack jee. pee. aiss. receiver aur ack jadatviya maap ikai (aaee. aim. yuu.) donon koo surakshit radar mein shamil kiya jaataa haye taaki munch kii sthiti aur gatividhiyon koo ekatra kiya jaa sakey aur nirdhaarit kiya jaa sakey kyonki yeh apane nirdisht vaahan key sheersh parr yatra kartaa haye. yeh jaankaari pranali koo radar kii backprojection imaging takneek kaa upayog karke saar imagery banaane kii anumati detee haye.
