nishkriya electronic roop seey scan kii gaee sarani

ack nishkriya electronic roop seey scan kii gaee sarani (pessa), jise nishkriya charanbaddh sarani key roop mein bhee jaanaa jaataa haye, ack antina haye jisamen radio tarangon kii kiran koo electronic roop seey vibhinn dishaaon mein ingit kiya jaa sakata haye (yaani, ack charanbaddh sarani antina), jisamen sabhi antina tatva ack ekal transmitter (jaise ack magnetron, ack cliestron yaa ack yatra tarang tube) aur/yaa receiver seey judey hotey hain. 
charanbaddh sarani kaa sabse badaa upayog radar mein hotaa haye. duniya mein sabse charanbaddh sarani radar pessa hain. nagrik microwave landing pranali kewal-sanchaarit sarani kaa upayog karati haye.
ack pessa ack sakriya electronic roop seey scan kiye gaye sarani (essa) antina key saath vipareet haye, jisamen pratyek antina tatva key liye ack alag transmitter aur/yaa receiver ikai hoti haye, joe sabhi ack computer dwara niyantrit hoti haye; essa mool pessa charanbaddh sarani praudyogiki kaa ack adhik unnat, bahumukhi doosari peedhi kaa sanskaran haye. donon key sankar bhee paae jaa sakate hain, jisamen upa-sarani shamil hain joe vyaktigat roop seey pessa seey milate-julate hain, jahaan pratyek upa-sarani kaa apana aar. aff. front aind hotaa haye. ack sankar drishtikon kaa upayog karate hue, isas key laabh (ee.jee.kaee swatantra beam) koo vaastavik isas kii tulanaa mein cumm laagat parr mahsoos kiya jaa sakata haye.
spandit radar pranali ack shaktishali radio transmitter seey antina koo jodkar sanket kii ack chhoti puls kaa utsarjan karati haye. transmitter koo taba disconnect curr diyaa jaataa haye aur antina koo ack samvedansheel receiver seey jodaa jaataa haye joe lakshit vastuon seey kissy bhee ecos koo badhaata haye. sanket key lautane mein lagane vaale samay koo mapkar, radar receiver vastu kii doori nirdhaarit curr sakata haye. receiver taba parinami output koo kissy prakaar key pradarshan key liye bhejata haye. transmitter tatva aamtaur parr cliestron tube yaa magnetron hotey they, joe uchch shakti staron taka aavrittiyon kii ack sankeern seema koo badhaane yaa utpann karane key liye upayukt hotey hain. akash key ack hisse koo scan karane key liye, ack gair-pessa radar antina koo bhautik roop seey vibhinn dishaaon mein sthanantarit kiya jaanaa chaahiye. isake vipareet, ack pessa radar kii kiran koo teji seey ack alag disha mein ingit karane key liye badala jaa sakata haye, buss nishkriya electronic roop seey scan kiye gaye sarani (pessa) key vibhinn tatvon key beach charan antar koo vidyut roop seey samaayojit karke.
1959 mein, darpa ney ack prayogaatmak charanbaddh sarani radar vikasit kiya jise electronic roop seey sanchaalit sarani radar essar kahaa jaataa haye. pahala module, ack raikhik sarani, 1960 mein puuraa kiya gayaa thaa. yeh ack/fps-85 kaa aadhar banaa.
1960 key dashak mein, niyantrit tareeke seey transmitter sanket mein deree karane mein saksham nae thhos-avastha upkaranon koo pesh kiya gayaa thaa. jisake kaaran pahale vyaavhaarik badey paimaane parr nishkriya electronic roop seey scan kii gaee sarani, yaa buss charanbaddh sarani radar huaa. pessa ney ack hii srot seey ack sanket liya, ise saikadon raaston mein vibhajit kiya, unamen seey kuchh koo chuninda roop seey vilambit kiya, aur unhein vyaktigat antena mein bheja. alag-alag antena seey radio sanket antariksh mein ativyaapi hotey hain, aur vyaktigat sanketon key beach hastakshep pattern koo kuchh dishaaon mein sanket koo majboot karane key liye niyantrit kiya jaataa haye, aur ise anya sabhi mein mute kiya jaataa haye. deree koo aasaani seey electronic roop seey niyantrit kiya jaa sakata haye, jisase antina koo sthanantarit kiye binaa beam koo bahut jaldi chalaaya jaa sakata haye. ack pessa paaramparik yaantrik pranali kii tulanaa mein bahut teji seey jagah kii matra koo scan curr sakata haye. electronics mein pragati key liye dhanyavaad, pessa ney kaee sakriya beemon kaa utpaadan karane kii kshamata koo jodaa, jisase way akash koo scan karna jaari rakh sakate hain, jabaki usee samay ardh-sakriya radar hoaming misaailon kaa pataa lagaane yaa margadarshan karane key liye kuchh lakshyon parr chhote beemon parr dhyaan kendrit curr sakate hain. 1960 key dashak mein pessa jaldi seey jahaajon aur badey nishchit sthaan parr vyaapak hoe gaye, jisake baad electronics key sikudane key saath vayu samvedak bhee they.
