Microwave antennas, suav nrog X-band horn antennas thiab high-gain waveguide probe antennas, 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, ntau zaus, thiab lub sijhawm raug.
1. Radiation Safety Standards
Kev cai txwv:
Microwave antennas ua raws li FCC/ICNIRP txwv tsis pub (piv txwv li, ≤10 W / m² rau X-band pej xeem cheeb tsam). PESA radar systems suav nrog kev txiav hluav taws xob tsis siv neeg thaum tib neeg mus txog.
Kev cuam tshuam zaus:
Ntau zaus (piv txwv li, X-band 8-12 GHz) muaj qhov tob tob tob (< 1mm hauv daim tawv nqaij), txo cov ntaub so ntswg kev puas tsuaj piv rau qis zaus RF.
2. Tsim kev nyab xeeb nta
Kav hlau txais xov Efficiency Optimization:
High-efficiency designs (> 90%) txo cov hluav taws xob tsis zoo. Piv txwv li, waveguide sojntsuam kav hlau txais xov txo cov sidelobes rau <–20 dB.
Shielding & Interlocks:
Tub rog/kev kho mob systems embed Faraday tawb thiab motion sensors los tiv thaiv raug xwm txheej.
3. Daim ntawv thov tiag tiag hauv ntiaj teb
| Scenario | Kev ntsuas kev nyab xeeb | Risk Level |
|---|---|---|
| 5G Base Chaw nres tsheb | Beamforming zam kev raug tib neeg | Tsawg |
| Tshav dav hlau Radar | Fenced exclusion zones | Tsis tsim nyog |
| Kev Kho Mob Imaging | Pulsed ua haujlwm (<1% lub voj voog ua haujlwm) | Tswj tau |
Xaus: Microwave antennas muaj kev nyab xeeb thaum ua raws li kev cai txwv thiab tsim kom zoo. Rau cov kav hlau txais xov siab, tuav> 5m nrug ntawm cov apertures nquag. Nco ntsoov xyuas cov kav hlau txais xov efficiency thiab tiv thaiv ua ntej xa mus.
