Yuav ua li cas hluav taws xob hluav taws xob cuam tshuam rau ib tus neeg tau txaus siab rau cov kws tshawb fawb tau ntau xyoo lawm. Qhov tshwm sim ntawm kev ua tiav kev tshawb fawb nyob rau hauv cheeb tsam no yog qhov tshwm sim ntawm xov tooj cua zaus riam phom, uas yog raws li cov cai tshiab lub cev (ONFP). Raws li cov kws tshaj lij, hom riam phom no tsis yog tuag taus. Kawm ntxiv txog xov tooj cua zaus riam phom hauv kab lus no.
Introduction
Xov tooj cua zaus riam phom yog riam phom tshwj xeeb uas siv hluav taws xob hluav taws xob. Lawv qhov kev khiav hauj lwm sib txawv ntawm 30 GHz (ntau zaus heev) thiab qis dua 100 Hz (ntau zaus tsawg). Xov tooj cua zaus riam phom (duab OFNP hauv qab no) kuj hu ua microwave lossis microwave. Cov peev txheej ntawm xov tooj cua zaus hluav taws xob hluav taws xob hluav taws xob (RFEM) tau tsim nyob rau hauv USSR thiab Asmeskas xyoo 1960s. Tom qab ntawd, lwm lub tebchaws tau txais kev siv thev naus laus zis.
yog dab tsiONFP?
Ib lub xov tooj cua zaus riam phom (RFW) yog lub tshuab hluav taws xob uas lub zog yog siv los ntawm cov hlau nplaum. Lub zog ntawm ONFP thiab cov khoom puas tsuaj yuav nyob ntawm seb qhov twg emitter teeb tsa cov kev taw qhia thiab dab tsi impulse xa cov teeb liab. Lub luag haujlwm ntawm cov riam phom microwave yog ua kom tsis muaj roj ntsha thiab cov khoom siv hluav taws xob. Tus qauv tsim muaj lub kav hlau txais xov los ntawm kev xa cov kab hluav taws xob, cov roj teeb uas muab lub zog. Yog hais tias lub hauv paus yog tawg (VO), ces lub RFO yog nruab nrog tshwj xeeb transducers: ferromagnetic, ferroelectric, piezoelectric thiab explosive magnetohydrodynamic generators.
khoom ntawm kev puas tsuaj
Raws li cov kws tshaj lij, xov tooj cua zaus riam phom hauv cov tub rog, uas yog hluav taws xob hluav taws xob hluav taws xob ntawm qhov tsawg thiab ultra-siab zaus, yog tsom rau cov neeg ua yeeb ncuab. Yog tias siv, cov tub rog yuav muaj teeb meem nrog cov kabmob tseem ceeb: lub plawv, lub hlwb, cov hlab ntsha, thiab lwm yam. Tsis tas li ntawd, cov kws tshawb fawb tau pom tias cov riam phom microwave tuaj yeem cuam tshuam cov tshuab hluav taws xob tau yooj yim. Nrog kev pab los ntawm kev cog lus magnetrons thiab klystrons, uas nws lub hwj chim tsis ncav cuag 1 GW, lawv "tawg" airfields, missiles, command posts thiab chaw. Siv lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm lub xov tooj cua zaus riam phom, cov tub rog cuam tshuam kev ua haujlwm ntawm cov tshuab ua lub luag haujlwm rau kev tswj cov riam phom thiab cov tub rog. Raws li cov kws tshaj lij, ntau lub tshuab hluav taws xob microwave mobile tau txais kev pabcuam hauv cov tebchaws tsim. Txawm li cas los xij, raws li cov kws tshaj lij, cov tub rog nyiam ua kom puas lub hom phiaj thiab tsis xav tias nws txaus los cuam tshuam lawv.
hluav taws xob cuam tshuam rau lub cev li cas?
Vim qhov tseeb tias lub cev sab hauv ntawm tus neeg, nws lub siab lub ntsws thiab tus cwj pwm yog tswj hwm los ntawm lub hauv paus ntawm lub paj hlwb thiab cov hlab plawv, cov kws tshawb fawb tab tom kawm seb cov riam phom microwave cuam tshuam rau lawv li cas. Thaum lub sij hawm cov kev ntsuam xyuas, cov developers ntawm lub microwave pom tias lub hauv paus paj hlwb yog heev susceptible rau microwaves, lub teeb liab siv ntawm tsis pub tshaj 10 MW / cm2.
Piv txwv li, ib qho kev kis tus neeg mus rau 'meter' thiab decimeter nthwv dej (30-30 txhiab MHz) tuaj yeem ua rau mob taub hau thiab nce kev chim siab. Tsis tas li ntawd, kev nco tsis zoo, kev ntshai tshwm sim, tus neeg tsis tuaj yeem txiav txim siab ntawm nws tus kheej thiab nyob rau hauv lub xeev kev nyuaj siab. Yog li, nws tau pom tseeb tias cov chaw hauv lub hlwb tuaj yeem tsim kev txhawb zog lossis, hloov pauv, raug tsim txom.
Microwave rau kev tawm tsam neeg phem
Vim qhov tseeb tias cov tshuab niaj hnub no muaj kev cuam tshuam rau cov riam phom microwave, nws cov ntsiab lus me me yog qhov txaus nyiam rau cov neeg ua phem. Qhov kom zoo dua ntawm ONFP yog qhov kev tawm tsam electromagnetic tuaj yeem nqa tawm qhov zais cia. Yog li ntawd, qhov khoom yuav tsis paub tias nws raug tawm tsam. Qhov no ua rau nws muaj peev xwm ua tau zoo sib xws dua. Tsis tas li ntawd, nws yuav muaj teeb meem los xam qhov chaw thiab nws qhov chaw. Tom qab lub microwave riam phom tawm tsam, tsis muaj ib yam dab tsi los yog pov thawj ntawm cov khoom. Kev tawm tsam microwave tuaj yeem tsom:
- infrastructure;
- computer centers;
- tshav dav hlau, khoom siv hluav taws xob thiab tsev txhab nyiaj;
- tsoom fwv cov koom haum;
- tub ceev xwm.
Ntxiv rau, nrog kev pab los ntawm ORF, cov neeg tawm tsam tuaj yeem nres tsheb thiab lub nkoj tsav tsheb, cuam tshuam cov khoom siv sib txuas lus, thiab ua rau lub PCs ua haujlwm tsis zoo.
Hais txog cov cuab yeej tiv thaiv
Koj tuaj yeem tiv thaiv koj tus kheej los ntawm xov tooj cua zaus riam phom yog tias koj siv cov koom haum thiab kev ntsuas. Piv txwv li, cov khoom yuav tsum tau tiv thaiv los ntawm RFO yog thawj zaug txiav txim. Tsis tas li ntawd, simulating muaj peev xwm tawm tsam, qhov tsis muaj zog tau nthuav tawm hauv nws. Yog tias nws yuav tsum tau ua kom ruaj ntseg RES, cov kws tshaj lij tsim cov khoom siv hluav taws xob tsis zoo rau nws. Thaum muaj kev tawm tsam tshwm sim, tag nrho RES system yuav tsis ua haujlwm, vim tias nws cov peev txheej yuav cia li ua haujlwm. Lawv kuj tseem siv cov kev teeb tsa tshwj xeeb uas tso tawm pulses mus txog 100 MHz. Shielding qauv, lim, fiber-optic kev sib txuas lus kab (FOCL) yog suav hais tias zoo. Hauv cov tshuab computer, cov khoom siv nco uas sib npaug sib npaug yog siv. Yog li ntawd, tom qab lub microwave tawm tsam, cov ntaub ntawv ntawm cov xov xwm yuav tsis poob irretrievably. Yog tias nws yog technically ua tau, ces kev tiv thaiv yog muab rau tag nrho cov khoom. Yog hais tias nws loj heev, ces nws muab faib ua ob peb cais blocks los yog compartments. Rau kev tiv thaiv sab hauv thiab sab nraud, kev tiv thaiv ib nrab yog muab, uas yog paub ntawm cov kws tshaj lij ua "Faraday tawb".
Cov cuab yeej yog ibgrounded thawv, rau kev tsim khoom uas siv cov khoom siv hluav taws xob zoo heev. Cov kab hlau, dhau los ntawm qhov screen sib txuas lus nrog lub ntiaj teb sab nraud, tau nruab nrog kev tiv thaiv FOCL ntxiv ntawm cov tswv yim thiab cov zis.
Piv txwv ntawm riam phom RF
RFO tuaj yeem ua ke rau hauv ib chav kawm nrog rau cov lasers thiab lwm yam khoom siv uas tsim cov khoom siv hluav taws xob thiab nruab nrab rau hauv kab. Microwave raug muab los ntawm electromagnetic munitions (EMBP). Raws li qhov zaus ntawm kev ua haujlwm, xws li RFOs raug suav tias yog ib leeg. Ntxiv nrog rau kev puas tsuaj los ntawm cov khoom tawg, RFO ua rau cov khoom siv hluav taws xob tsis ua haujlwm nrog ultra-wideband pulses. Cov tshuab hluav taws xob yog lub luag haujlwm rau lub zog ntawm EMBP, uas hloov cov tshuaj siv hluav taws xob ntawm VO rau hauv hluav taws xob hluav taws xob. Hauv Tebchaws Meskas, RFO tau tsim los rau tub ceev xwm ntawm 96 GHz., ua rau kub hnyiab hauv lub hom phiaj ntawm kev tawm tsam. Qhov chaw uas cov hluav taws xob tau teeb tsa yog lub tsheb. Cov cuab yeej siv tau zoo nyob rau hauv ib lub vojvoog ntawm 200 m. Tsim los cuam tshuam kev sib tw. Hauv tebchaws Russia, NAGIRA radar ntawm 150 Hz tau tsim los ntes cov nyoob hoom qav taub. Los ntawm kev tsim cov luv luv thiab muaj zog (600 MW) pulses nrog zaus ntawm 10 GHz, nws pom cov nyoob hoom qav taub hauv ib lub vojvoog ntawm 150,000 m ntawm qhov siab ntawm 50 m. Raws li cov kws tshaj lij, RFO cov cuab yeej siv tau zoo heev: nrog cov roj teeb thiab lub kav hlau txais xov, a microwave riam phom tuaj yeem haum rau hauv rooj plaub me me.
Nyob hauv kaw
Qhov zoo ntawm cov riam phom microwave yog tias lawv tsis nyob ntawm kev xa cov mos txwv raws sijhawm. Yuav kom RFO ua haujlwm, nws yuav tsum tau muab hluav taws xob nkaus xwb. Txij li thaum qhov kev puas tsuaj mus txog lub hom phiaj nrogqhov ceev ntawm lub teeb, nws tsis muaj txoj kev los maneuver thiab deflect lub nres.
