Cov kav hlau txais xov microwave, suav nrog cov kav hlau txais xov X-band horn thiab cov kav hlau txais xov high-gain waveguide probe, muaj kev nyab xeeb thaum tsim thiab ua haujlwm kom raug. Lawv txoj kev nyab xeeb nyob ntawm peb yam tseem ceeb: lub zog ceev, qhov ntau zaus, thiab lub sijhawm raug.
1. Cov Qauv Kev Nyab Xeeb Txog Kev Siv Hluav Taws Xob
Cov Kev Txwv Cai:
Cov kav hlau txais xov microwave ua raws li FCC/ICNIRP cov kev txwv kev raug hluav taws xob (piv txwv li, ≤10 W/m² rau thaj chaw pej xeem X-band). PESA radar systems suav nrog kev txiav hluav taws xob tsis siv neeg thaum tib neeg los txog.
Kev Cuam Tshuam Zaus:
Cov zaus siab dua (piv txwv li, X-band 8–12 GHz) muaj qhov tob nkag mus tob (<1 hli hauv daim tawv nqaij), txo qhov kev pheej hmoo ntawm kev puas tsuaj ntawm cov nqaij piv rau RF zaus qis dua.
2. Cov yam ntxwv kev nyab xeeb ntawm kev tsim qauv
Kev Txhim Kho Antenna Zoo:
Cov qauv tsim ua haujlwm tau zoo (>90%) txo cov hluav taws xob tsis ncaj. Piv txwv li, cov kav hlau txais xov waveguide probe txo cov sidelobes kom <–20 dB.
Kev Tiv Thaiv & Kev Sib Txuas:
Cov txheej txheem tub rog/kev kho mob muab Faraday cages thiab cov sensors txav mus los kom tiv thaiv kev raug mob tsis raug.
3. Cov Kev Siv Hauv Lub Ntiaj Teb Tiag
| Xwm txheej | Kev Ntsuas Kev Nyab Xeeb | Qib Kev Pheej Hmoo |
|---|---|---|
| 5G Chaw Nres Tsheb | Beamforming zam kev raug tib neeg | Qis |
| Tshav Dav Hlau Radar | Cov cheeb tsam uas muaj laj kab thaiv | Tsis tseem ceeb |
| Kev Kho Mob Duab | Kev ua haujlwm pulsed (<1% lub voj voog ua haujlwm) | Tswj tau |
Xaus Lus: Cov kav hlau txais xov microwave muaj kev nyab xeeb thaum ua raws li cov kev cai lij choj thiab kev tsim qauv kom raug. Rau cov kav hlau txais xov siab, khaws cia kom deb > 5m ntawm qhov qhib qhib. Ib txwm xyuas kom meej tias lub kav hlau txais xov ua haujlwm zoo thiab kev tiv thaiv ua ntej xa mus.
