Hamwe nogukoresha kwinshi kwikoranabuhanga rya elegitoroniki yibikoresho bya gisirikare (cyane cyane indege), akamaro k’ubushakashatsi ku gukwirakwiza amashanyarazi kuri electronique biranga intego za radar byagaragaye cyane.Kugeza ubu, harakenewe byihutirwa uburyo bwo gutahura ibimenyetso bya electromagnetiki ikwirakwiza biranga intego, bishobora gukoreshwa mu isesengura ryujuje ubuziranenge bw’ubujura bwa electromagnetic hamwe n’ingaruka z’ubujura.Ibipimo bya Radar Cross Cross (RCS) nuburyo bwingenzi bwo kwiga amashanyarazi akwirakwiza ibintu biranga intego.Nka tekinoroji yateye imbere mubijyanye no gupima ikirere no kugenzura, gupima intego ya radar ikoreshwa cyane mugushushanya radar nshya.Irashobora kumenya imiterere nubunini bwintego mugupima RCS kumyumvire yingenzi.Ikigereranyo cyo hejuru cyo gupima radar mubusanzwe ibona amakuru yintego mugupima icyerekezo cyerekanwe, ibiranga radar iranga nibiranga Doppler, muribyo gupima ibipimo bya RCS ni ugupima ibimenyetso biranga intego.
Ibisobanuro no gupima ihame rya radar ikwirakwiza
Igisobanuro cyo gutatanya Imigaragarire Iyo ikintu kimurikirwa numurongo wa electromagnetic, imbaraga zacyo zizatatana mubyerekezo byose.Ikwirakwizwa ryingufu zitandukana biterwa nuburyo, ubunini, imiterere yikintu ninshuro n'ibiranga umuraba.Uku gukwirakwiza ingufu kwitwa gutatanya.Ikwirakwizwa ryingufu zingufu cyangwa gukwirakwiza imbaraga mubisanzwe birangwa no gutatanya igice cyambukiranya, aricyo gitekerezo cyintego.
Ibipimo byo hanze
Ikibanza cyo hanze RCS gupima ni ngombwa mu kubona amashanyarazi akwirakwiza ibintu binini binini byuzuye [7] Ikizamini cyo hanze cyagabanijwemo ikizamini cya dinamike n'ikizamini gihamye.Igipimo cya RCS gifite imbaraga gipimwa mugihe cyo kuguruka kwizuba ryizuba.Igipimo cya dinamike gifite ibyiza bimwe byo gupima static, kuko bikubiyemo ingaruka zamababa, ibice bya moteri, nibindi kumurongo wa radar.Ihuza kandi imiterere-yimiterere ya kure kuva 11 kugeza 11 Nyamara, igiciro cyayo ni kinini, kandi cyatewe nikirere, biragoye kugenzura imyifatire yintego.Ugereranije nikizamini cya dinamike, inguni irakomeye.Ikizamini gihamye ntigikeneye gukurikirana urumuri rwizuba.Intego yapimwe yashyizwe kumurongo uhinduranya antene.Gusa mugucunga inguni yo kuzenguruka, gupima omni-icyerekezo cyo gupima intego yapimwe 360 irashobora kugerwaho.Kubwibyo, ikiguzi cya sisitemu nigiciro cyibizamini biragabanuka cyane Mugihe kimwe, kubera ko hagati yintego ihagaze ugereranije na antenne, kugenzura imyifatire ni ndende, kandi gupima birashobora gusubirwamo, ntibitezimbere gusa ukuri kwa gupima no guhinduranya, ariko kandi biroroshye, mubukungu, no kuyobora.Igeragezwa rihamye ryoroshye kubipimo byinshi byintego.Iyo RCS igeragezwa hanze, indege yubutaka igira ingaruka zikomeye, kandi igishushanyo mbonera cyibizamini byo hanze cyerekanwe ku gishushanyo cya 2 Uburyo bwa mbere bwazanye bwa mbere kwari ugutandukanya intego nini zashyizwe hagati yindege yubutaka, ariko mumyaka yashize ntibishoboka kubigeraho Birazwi ko inzira nziza yo guhangana nindege yubutaka ari ugukoresha indege yubutaka nkuwitabira gahunda yo kurasa, ni ukuvuga gushyiraho ibidukikije byerekana ubutaka.
Ibipimo byo mu nzu
Ikizamini cyiza cya RCS kigomba gukorerwa mubidukikije bitarangwamo akajagari.Umwanya wibyabaye umurikira intego ntabwo bigira ingaruka kubidukikije.Icyumba cya microwave anechoic itanga urubuga rwiza rwo gupima RCS murugo.Urwego rwo kwerekana inyuma rushobora kugabanuka mugutegura neza ibikoresho bikurura, kandi ikizamini gishobora gukorerwa ahantu hagenzurwa kugirango bigabanye ingaruka zibidukikije.Agace kingenzi cyane ka microwave anechoic chambre yitwa ahantu hatuje, kandi intego cyangwa antenne igomba gupimwa ishyirwa ahantu hatuje Igikorwa cyayo nyamukuru nubunini bwurwego rwazimiye ahantu hatuje.Ibipimo bibiri, ibyerekanwe hamwe na radar yambukiranya igice, bikunze gukoreshwa nkibipimo byerekana isuzuma rya microwave anechoic chambre [.. Ukurikije imiterere yumurima wa antenna na RCS, R ≥ 2IY, bityo igipimo D cyumunsi ni kinini nini, kandi uburebure bwumurongo ni bugufi cyane.Intera yikizamini R igomba kuba nini cyane.Kugira ngo iki kibazo gikemuke, tekinoroji yo mu rwego rwo hejuru ikora neza kandi yashyizweho kuva mu myaka ya za 90.Igishushanyo cya 3 cyerekana ibishushanyo mbonera byerekana ibishushanyo mbonera.Urwego ruciriritse rukoresha sisitemu yerekana ibintu bigizwe no guhinduranya paraboloide kugirango ihindure imiraba ya serefegitura mu ndege y’indege ku ntera ngufi ugereranije, kandi ibiryo bishyirwa ku cyerekezo Icyerekezo cyerekezo cy’ibintu, bityo izina "compact".Kugirango ugabanye taper na waviness ya amplitude ya zone ihagaze ya intera ihagaze, impande zubuso bugaragaza zitunganyirizwa.Mu gupima gusakara mu nzu, kubera kugabanuka k'ubunini bw'icyumba cyijimye, ibyumba byinshi byijimye bikoreshwa nk'icyitegererezo cyo gupima urugero.Isano iri hagati ya RCS () yicyitegererezo cya 1: s na RCS () yahinduwe kuri 1: 1 ingano yintego nyayo ni imwe + 201gs (dB), kandi inshuro yikizamini cyikigereranyo igomba kuba inshuro inshuro nyayo. igipimo cyizuba cyizuba f.
