Microwaves yog zoo rau kev xa xov los ntawm ib qhov chaw mus rau lwm qhov vim tias lub zog microwave tuaj yeem nkag mus rau huab cua, nag lossis daus, huab, thiab pa taws. Cov microwaves luv dua yog siv nyob rau hauv tej thaj chaw deb sensing. Cov microwaves no yog siv rau radar zoo li doppler radar siv hauv huab cua huab cua.
Puas txhua lub radars siv microwaves?
Thaum me dua 30cm (1 GHz thiab siab dua) lawv raug hu ua microwaves. Ntau lub tshuab radar siv microwaves vim cov kav hlau txais xov tuaj yeem ua rau lub cev me dua li qhov wavelength txo.
Puas radars siv xov tooj cua lossis microwaves?
Radar cov ntaub ntawv tuaj yeem siv los txiav txim cov qauv ntawm cov cua daj cua dub thiab pab nrog kwv yees qhov hnyav ntawm cua daj cua dub. Lub zog yog emissions nyob rau hauv ntau zaus thiab wavelengths los ntawm loj wavelength xov tooj cua tsis mus rau luv wavelength gamma rays. Radars emit microwave zog, ntev wavelength, highlighted daj.
Vim li cas microwaves siv hauv radar tsis yog xov tooj cua?
Microwaves yog electromagnetic tsis muaj zaus ntawm 1 GHz txog 300 GHz. Txij li thaum lawv yog microwaves ntawm me me wavelengths, lawv muaj peev xwm kis tau raws li ib tug beam teeb liab nyob rau hauv ib qho kev taw qhia. Tsis tas li ntawd, microwaves tsis khoov ib puag ncig ntawm txhua qhov kev cuam tshuam los ntawm lawv txoj kev. Li no, microwaves yog siv nyob rau hauv radars.
Doppler radars siv microwaves li cas?
A Doppler radar yog ib qho tshwj xeeb radar uas siv cov nyhuv Doppler los tsim kev tshaj tawmcov ntaub ntawv hais txog cov khoom ntawm qhov deb. Nws ua qhov no los ntawm bouncing lub microwave teeb liab tawm ntawm lub hom phiaj xav tauthiab tshuaj xyuas seb qhov khoom li cas tau hloov pauv qhov zaus ntawm lub teeb liab rov qab.
Pom zoo:
Thaum siv vim li cas thiab yog vim li cas?
Vim li cas thiab qhov twg ntawm qee yam yog vim li cas rau nws. Txawm tias cov thawj coj ua tiav yuav tsum tau nug txog vim li cas thiab yog li ntawd ntawm lawv qhov kev ua. Nws tsis txaus siab tham txog vim li cas thiab yog li ntawd nws lub sijhawm nyob txawv teb chaws.
Puas radar siv microwaves?
Radar thev naus laus zis suav hais tias yog lub zog siv hluav taws xob nyob deb vim nws nquag xa lub microwave mem tes thiab hnov lub zog rov qab los. Doppler Radar, Scatterometers, thiab Radar Altimeters yog cov piv txwv ntawm cov cuab yeej siv hluav taws xob siv hluav taws xob uas siv microwave frequencies.
Microwaves siv rau dab tsi?
Ib qho siv ntau tshaj plaws ntawm microwaves yog kom sov zaub mov sai. Microwave qhov cub tuaj yeem ua tau vim tias microwaves tuaj yeem siv los xa cov thermal zog. YYuav siv cov microwaves dab tsi? Lub qhov cub microwave yog cov khoom siv hauv chav ua noj muaj ntau yam uas muaj ntau yam kev siv.
Qhov kub npaum li cas ua microwaves ua noj?
Qhov nruab nrab WATTAGE ntawm lub microwave yog 700-1200 watts. Qhov no yog lub hwj chim uas yog lub hauv paus rau lub sij hawm ua noj nyob rau hauv feem ntau cov zaub mov txawv hauv microwave, tshwj tsis yog hais tias txawv. Qhov no yuav zoo li qhov "
Microwaves cua sov zaub mov li cas?
Microwaves yog tsim nyob rau hauv qhov cub los ntawm ib lub raj electron hu ua magnetron. Cov microwaves tau pom nyob rau hauv cov hlau sab hauv ntawm qhov cub uas lawv tau nqus los ntawm cov zaub mov. Microwaves ua rau dej molecules hauv cov zaub mov kom vibrate, ua kom sov ua zaub mov.
