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.

Puas radar siv microwaves lossis xov tooj cua tsis?

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 tso tawm lub zog microwave, lub sijhawm ntev dua, taw qhia daj.

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.

Vim li cas microwaves siv hauv radar navigation?

Microwaves raug suav hais tias tsim nyog rau cov tshuab radar siv hauv dav hlau navigation vim lawv muaj qhov luv wavelength ntau yam (10- 3m txog 0.3 m), uas ua rau lawv haum rau kev sib txuas lus ntev.

Yuav siv hluav taws xob hluav taws xob dab tsi rau radar?

Radars feem ntau ua haujlwm ntawm xov tooj cua zaus (RF) ntawm 300 MHz thiab 15 GHz. Lawv tsim EMFs uas hu ua RF teb. RF teb nyob rau hauv ib feem ntawm lub electromagnetic spectrumpaub tias muaj kev cuam tshuam txawv ntawm tib neeg lub cev.
