Lub tsev hluav taws xob tiv thaiv hluav taws xob yog lub tsev ntsuas kev ua haujlwm rau cov tuam tsev (ntau zaus, qee qhov chaw nyob hauv cov tsev zoo li no) uas tsis muaj kev cuam tshuam nrog hluav taws xob yoj xau.
Taw qhia: Lub tsev hluav taws xob tiv thaiv hluav taws xob yog kev ntsuas kev tsim kho kom sib cais nrog hluav taws xob kev cuam tshuam nrog hluav taws xob plotion weakage. Electromagnetic thev nyiaj thev naus laus zis tau tsim nyob rau xyoo 1940 thiab tau nce zuj zus nyob rau xyoo 1950. Nws cov haujlwm yog los tiv thaiv kev cuam tshuam hluav taws xob sab nraud hluav taws xob sab nraud thiab txhawm rau txhawm rau txhawm rau txhawm rau hauv sab hauv tsev Electromagnetic Way. Lub hom hluav taws xob tau muab faib ua peb pawg raws li cov yam ntxwv raws li kev cuam tshuam ntawm kev cuam tshuam, sib nqus ntawm cov kab kev cuam tshuam ntawm lub zog hluav taws xob. Raws li lawv cov yam ntxwv, coj kev ntsuas qauv coj los ua kom sib xyaw ua ke cov qauv ntawm cov khoom siv sab nraud lossis cov tawv nqaij tiv thaiv tau ua kom lawv muaj kev ua haujlwm ntawm hluav taws xob hluav taws xob hluav taws xob sib txawv. Raws li daim ntawv ntawm qhov chaw, nws tau muab faib ua hom tsau, kev sib sau ua hom phiaj, dai hom (piv txwv li lub hom phiaj hlau), thiab lub tsho tiv thaiv txheej txheem hauv tsev). Lub plhaub hlau tau tsim los ntawm kev siv hlau tiaj tus phiaj, perforated hlau phaj, ib leeg-txheej lossis hlau xaim sib dhos cov khaubncaws sab nraud povtseg, thiab hlau cim hlau mesh.
Txij li thaum xyoo 1950, hluav taws xob tiv thaiv tshuab thiab kev thaiv kev tsim cov qauv tsim tau ua kom zoo meej. Tam sim no tau kawm thiab thov yog cov hlau hmoov tshuaj tsuag lub tsho, thiab cov ntaub ntawv tiv thaiv hlau ua thiab tswj cov khoom siv hluav taws xob.
Cov kev tiv thaiv ntawm daim ntawv thov: Lub tsev hluav taws xob tiv thaiv hluav taws xob yog siv hauv ob qho:
Ua ntej, los tiv thaiv kev cuam tshuam rau sab nraud hluav taws xob hauv hluav taws xob, xws li TV kev lag luam, xws li kev kuaj hluav taws xob hauv xov tooj cua, kev siv hluav taws xob hauv tshuab hluav taws xob, thiab lwm yam ..
Thib ob, kom tiv thaiv sab hauv tsev hluav taws xob hluav taws xob hluav taws xob tsis sib xws los ntawm kev tawm mus thiab raug kev cuam tshuam tawm thiab raug kev cuam tshuam, thiab ua rau tsis pub lwm tus tsis pub lwm tus paub. Microwave radar kev ua haujlwm, kev sib txuas lus kho qhov muag ntsuas, ultra-nplai-teev cov kev ntsuas kev sib xyaw ua ke, thiab qhia txog qhov ntsuas hluav taws xob, thiab qhia txhua yam thaum ntxov los ntawm kev xau.
Cov yam ntxwv thiab kev faib tawm. Raws li cov yam ntxwv ntawm cov yam ntxwv ntawm kev cuam tshuam tau sib faib tau muab faib ua peb pawg: cov kab hauv kev sib cuam tshuam, thiab cov kab sib sib zog ntawm hluav taws xob kev cuam tshuam. Lub tsev siv hluav taws xob cuam tshuam nrog kev ntsuas cov qauv txheej txheem hauv ntau hom kev tiv thaiv hluav taws xob tau ua rau cov chaw tsim khoom sab nraud kom ua rau lub tsev tiv thaiv hluav taws xob. Nws cov ntaub ntawv tau muab faib ua chav sib faib ua si, chav ua haujlwm hauv chav tsev, dai hom (piv txwv li cov chav thaiv hlau (piv txwv li cov ntaub thaiv npog txheej sab hauv qab ntawm qhov chaw ntawm qhov chaw; Raws li lub plhaub hlau thiab cov qauv, nws tau muab faib ua hlau tiaj lub phaj, ib-txheej hlau plhaub mesh plhaub thiab honeycomb hlau Mesh plhaw chav tsev.
Kev thaiv kev xaiv chav xaiv cov ntaub ntawv tiv thaiv, cov qauv kev tiv thaiv Weepitality, thiab kev tsim kho hluav taws xob, thiab kev tsim kho hluav taws xob, thiab siv thiab kho yuav tsum txiav txim siab txiav txim siab. Feem ntau, qhov chaw me me uas yooj yim los tiv thaiv yog siv, tsis muaj qhov rai lossis aluminium daim tawv ntoo yog siv es tsis siv cov khoom siv kim kims.
Cov ntaub ntawv thiab cov qauv kev teeb tsa cov chav nrog cov kev nthuav dav yuav tsum siv cov ntaub thaiv npog thiab cov qauv qauv. Cov txheej txheem ntawm kev caij nkoj ua ntej cov qauv hlau hauv cov qauv tiv thaiv sab nraud muaj kev tiv thaiv zoo dua, tab sis tus nqi yog qhov siab. Cov txheej txheem ntawm kev siv hlau perforated daim hlau rau kev ua tiav muaj cov nyhuv zoo, tuaj yeem txo cov txiaj ntsig tuag thiab txuag tau cov roj ntsha, tab sis tus nqi kuj siab. Cov txheej txheem ntawm kis hlau xaim hlau ntxig txheej txheej tswj hwm, tab sis yooj yim rau kev tiv thaiv kev tiv thaiv hluav taws xob yog qhov kev nkag siab. Cov txheej txheem ntawm txau hlau hmoov rau ntawm cov npoo av nyob sab hauv tsev yog cov kev siv hlau ua ntej, tab sis yooj yim thiab muaj ntom ntom thiab ruaj khov.
Kev kho mob kis yog qhov tseem ceeb ntawm kev tiv thaiv chav tsim. Txhawm rau kom muab cov voj voos uas yuav ua rau lub zog hluav taws xob, xws li cov ntaub hlau sib txawv uas yuav tsum tau ua rau cov ntaub hlau uas sib txawv, thiab cov ntaub hlau sib txawv Cov ntawv sau caij nplooj ntoos hlav, honeycomb WaveGuides, lim fais fab, thiab lwm yam qhia txog cov txheej txheem sab hauv, qhov twg thiab cov npoo av thiab lub qhov rooj. Txhawm rau tiv thaiv kev tsim cov hws rau hluav taws xob siv cov xov hlau, thiab lub qhov rooj thiab qhov rai sash overlaps los thaiv electromagnetic vuag. Ntawm cov yeeb nkab qhib cov chav tsev, lub lim fais fab tau ntxiv, uas tsis cuam tshuam nrog cov yeeb nkab thiab tuaj yeem tiv thaiv hluav taws xob tsis los ntawm kev nkag mus thiab tawm.
