Radar ya AESA na PESAni ukugereranya imiterere ibiri ya "array architectures" ya "electronic scanned". Byombi biyobora "radar beam" binyuze mu kugenzura "phase" mu bice byinshi bya "antenna", bidakoresheje "mechanical" ku mpinduka zose zigaragaza aho ibintu bihinduka. Itandukaniro rikomeye ni aho imbaraga za RF zikorwa kandi zigagenzurwa: "passive electronic scanned array" (PESA) muri rusange ikoresha "centralized transmitter/receiver path", mu gihe "active electronic scanned array" (AESA) ikwirakwiza "transmit/receive modules" nyinshi mu gice cy'imbere cy'aho ibintu biherereye.
Ni irihe tandukaniro riri hagati ya AESA na PESA Radar?
Itandukaniro riri hagati ya AESA na PESA radar ahanini ni imiterere ya RF inyuma y’urutonde rw’ibikoresho. Imbonerahamwe iri hepfo igaragaza muri make imikoranire y’ubuhanga ikunze kwitabwaho mu gihe cyo gushushanya no gusuzuma sisitemu ya radar.
| Kugereranya | Radar ya PESA | Radar ya AESA |
|---|---|---|
| Imiterere ya RF | Isoko ya RF ifite ingufu nyinshi ikwirakwizwa binyuze mu muyoboro w'itumanaho n'ibikoresho byo guhindura ibyiciro | Module nyinshi zo kohereza/kwakira zikwirakwijwe zihujwe n'ibintu bya antene cyangwa subarrays |
| Uburyo bwo kuyobora imirasire | Uburyo bwo kugenzura imikorere y'ikoranabuhanga mu mwobo wose | Igenzura ry'urwego rw'amashanyarazi n'ubwinshi bw'amajwi hamwe n'uburyo bworoshye bwo gukora amajwi |
| Ubushobozi bwo gukora imirimo myinshi | Biterwa n'imiterere ya sisitemu n'umukoresha wa gahunda | Bikwiriye cyane mu gushakisha, gukurikirana no gukora izindi mirimo byihuse |
| Kwihanganira amakosa | Kunanirwa kwa RF-chain yo hagati bishobora kugira ingaruka zikomeye ku rwego rwa sisitemu | Gutsindwa kwa module imwe ku yindi akenshi bigabanya imikorere buhoro buhoro aho guhagarika urutonde rwose |
| Ingorane | Muri rusange modules za RF zikora nkeya | Gucunga, kugenzura, no guhuza ubushyuhe bisaba imbaraga nyinshi. |
Radar ya PESA ni iki?
A urutonde rw'ibikoresho byasuzumwe hakoreshejwe ikoranabuhanga bidakoreshejweikoresha uburyo bwo kohereza/kwakira buhuriweho n'imbaraga nyinshi. Ingufu za RF zinyuzwa mu muyoboro w'itumanaho ujya ku bintu byinshi bitanga urumuri, mu gihe ibikoresho bihindura ibice bigenzurwa n'ikoranabuhanga bihindura urwego kuri buri kintu kugira ngo biyobore urumuri. Urukurikirane ubwarwo rwitwa passive kuko aho hantu hatari module yuzuye yo kohereza/kwakira kuri buri kintu.
Ibiranga by'ingenzi bya PESA
- Guskana hakoreshejwe ikoranabuhanga:umuyoboro ushobora kwimurwa vuba hatabayeho kwimura imiterere y'antene yuzuye.
- Ikoreshwa rya RF rihuriweho mu buryo buhuriweho:imashini isanzwe ikwirakwiza umwuka binyuze mu bice bikwirakwiza amakuru n'ibihinduranya by'impinduka.
- Imiterere y'ubwubatsi yashyizweho:Ikoranabuhanga rya PESA rikoreshwa muri sisitemu nyinshi za radar zikoreshwa ku butaka, mu mazi no mu kirere.
- Ubushobozi bushingiye kuri sisitemu:Ubushobozi bwo gukurikirana, uburyo bwo gupima umuraba n'umuvuduko wo gushakisha biterwa n'igishushanyo cyuzuye cya radar, ntabwo biterwa gusa no kumenya niba aho umwobo ari PESA.
Ibyiza n'imbogamizi bya PESA
PESA ishobora gutanga ubuyobozi bw'amashanyarazi bunoze hamwe na module nke zikora kurusha AESA. Ibi bishobora kugabanya uburyohe bw'ibikoresho bya RF. Ariko, igihombo cya feed-network no kwishingikiriza kuri transmitter yo hagati bishobora kubangamira imikorere myiza no kwihanganira amakosa. PESA ntigomba kwitwa ko ari inshuro imwe gusa cyangwa ngo igerweho ku ntego imwe; ibyo biranga biratandukanye bitewe n'ishyirwa mu bikorwa rya radar.
Radar ya AESA ni iki?
An urutonde rw'ibikoresho byasuzumwe hakoreshejwe ikoranabuhangaIrimo module nyinshi zo kohereza no kwakira ibintu muri antene. Module isanzwe igenzura igice kimwe cya antene cyangwa agace gato k'inyuma. Igenzura ry'ikoranabuhanga rihuza icyiciro, ubwinshi, igihe n'imyitwarire y'ishusho y'umuraba kugira ngo radar ibashe kuyobora no gushyira igihe ku mirasire mu buryo bworoshye.
Ibiranga by'ingenzi bya AESA
- Moduli za RF zikwirakwijwe:Gutanga amashanyarazi no kuyakira bikwirakwizwa mu mwobo wose.
- Kugenzura imirasire y'amashanyarazi:Aho umuraba uherereye n'imiterere y'umuraba bishobora guhinduka vuba kugira ngo bishyigikire imikorere yo gushakisha, gukurikirana, gushushanya no gutumanaho aho sisitemu yagenewe.
- Gusenyuka kw'ibintu mu buryo bwiza:Kunanirwa kwa modules ku giti cyazo akenshi bituma imikorere igabanuka buhoro buhoro aho gutakaza burundu urutonde.
- Gupima no gukenera ubushyuhe:guhuza module, gukuraho ubushyuhe, gukwirakwiza ingufu na porogaramu yo kugenzura ni bimwe mu bintu by'ingenzi mu guhuza AESA.
Ibyiza n'imbogamizi bya AESA
Imiterere ya AESA ishobora gutanga icyizere cyo hejuru, kugenzura imiraba y’amashanyarazi mu buryo bworoshye, gukora gahunda yihuse y’imirimo no gukoresha uburyo bwo guhangana n’ibiza mu buryo bw’ikoranabuhanga. Izi nyungu zizanwa n’umubare munini w’ibikoresho, imbaraga zo gupima, ibisabwa mu gukonjesha n’igiciro. Imikorere nyayo iterwa n’ingano y’aho ufungura, inshuro z’imikorere, imbaraga zo gusohora module, imiterere y’urusaku, bandwidth, intera y’ibice, inguni yo gushakisha no gutunganya ibimenyetso.
Ni ikihe cyiza kurusha ibindi: AESA cyangwa PESA?
Nta gisubizo rusange gihari. AESA ikunze gukundwa iyo imikorere myinshi, kwihanganira amakosa no guhindagurika kw'imiterere y'amajwi ari byo by'ingenzi. PESA ishobora gukomeza kuba ingirakamaro iyo intego ikenewe ishobora kuzuzwa hakoreshejwe uruhererekane rwa RF ruhuriweho hamwe n'imiterere yoroshye ya module ikora. Abahanga mu by'imashini bagomba kugereranya ibisabwa na sisitemu ipimwa aho guhitamo gusa mu magambo ahinnye.
Imiterere y'ikwirakwira ry'ibintu nayo ni ingenzi. Inzira nyinshi, kuziba kw'ibintu n'ingendo bishobora guhindura urwego rwakiriwe n'uburyo ibipimo bisubiramo, bityo isuzuma rya radar rigomba kuba rirebaumuyoboro udafite insinga ugenda ushirairuhande rw'imiterere y'amatsinda.
- Sobanura ingano y'imikorere n'umuvuduko w'amakuru ako kanya.
- Shyiraho ibisabwa mu gupima, gupima, gupima imiterere y'urukiramende n'uburyo bwo gupima imiterere y'urukiramende.
- Kumenya igihe cyo gushakisha, gukurikirana no gukoresha igihe kinini.
- Suzuma imbaraga za transmitter, uburyo bwo kwakira amakuru n'uburyo bwo guhindura imikorere.
- Suzuma imbogamizi z'ubushyuhe, amashanyarazi, mekanike n'ibidukikije.
- Uburyo bwo gupima gahunda, kugenzura no gupima antene.
Antena za Array n'Inkunga y'Ikizamini cya RF bitangwa na RF MISO
RF MISO ni uruganda rwa RF na microwave antene rukaba n'umucuruzi utanga ubufasha mu bushakashatsi ku ntene, gupima no guhuza sisitemu. Ntitwerekana radar yuzuye nk'antene imwe isanzwe. Ahubwo, injeniyeri zishobora gusuzuma ibice bireba no kugerageza ibisubizo hakurikijwe umurongo wa frequency ukenewe, inyungu, polarization, interface na mekanike.
Suzuma RF MISOibicuruzwa bya antene zo mu bwoko bwa 'array', antene z'imbonerahamwe, imashini zipima umurabanaubushobozi bwo gupima anteneKu isuzuma ry'umushinga, tanga umurongo ngenderwaho w'imikorere, polarization, gain target, beamwidth, ibisabwa mu gushakisha, connector cyangwa waveguide interface, imbogamizi zo gushyiraho hamwe n'imiterere y'ibidukikije.
Ibibazo Bikunze Kubazwa
Ese AESA na PESA bashobora gukoresha radar zombi mu buryo bw'ikoranabuhanga?
Yego. Imiterere yombi ikoresha imibanire y’ibyiciro bigenzurwa mu bice bitandukanye kugira ngo iyobore imirabyo idakoresheje ikoranabuhanga mu kuzunguruka umwobo wose kuri buri cyerekezo cyo gushakisha.
Ese AESA ihora ari nziza kurusha PESA?
Oya. AESA itanga inyungu zikomeye mu buryo bworoshye, gukoresha ingufu nyinshi no gukora ibintu byinshi, ariko inatanga ibikoresho bifatika, imicungire y'ubushyuhe n'uburyo bwo gupima. Guhitamo neza biterwa n'inshingano n'ibisabwa muri sisitemu.
Kuki AESA ishobora gukomeza gukora nyuma y'uko module inaniwe?
Kubera ko RF ikorwa kandi igakwirakwizwa muri module nyinshi. Umubare muto w'ibibazo bya module ubusanzwe bigabanya imikorere y'aperture iboneka buhoro buhoro, nubwo ingaruka nyazo ziterwa n'imiterere y'urutonde n'aho ikibazo giherereye.
Ni ibihe bipimo bya antene bigira akamaro mu isuzuma rya radar?
Ibipimo by'ingenzi birimo ingano y'imikorere, bandwidth, polarization, gain, beamwidth, sidelobe level, cross-polarisation, placement elements, scan loss, impedance match, power handling hamwe n'imikorere y'amashanyarazi na mekanike.
Ganira ku bisabwa kuri Antena za RF zawe
Vugana na RF MISO urebe aho ukoresha inshuro nyinshi n'ibisabwa mu rwego rwa tekiniki kugira ngo ubone ubufasha mu guhitamo ibicuruzwa.
