還是最後．．．
只是誤會一場？

請教 NCC 官員 Miss.藍
車用雷達
是她負責的
目前
要先提供波段瀕率
才能確認可否進口?
至於
引用規範
她要我自己找
低功率設瀕規範?

TECHNICAL ASPECTS
Forward-looking vehicle radar typical detection range varies from about 300 to 600 feet (about 100 to 200 meters). Radar transmit power (and range) is greatly reduced (-25 dB for forward radar, -22 dB for side and rear radar) when vehicle traveling less than 1 kmh (0.6 mph).
VEHICLE RADAR LIMITS
--------------------------------------------------
FCC RULES, PART 15, SECTION 15.253 (1998 Aug 7)
FREQUENCY TOLERANCE BAND
46.8 GHz ± 200 MHz 46.7 - 46.9 GHz
76.5 GHz ± 500 MHz 76.0 - 77.0 GHz
POWER DENSITY at 3 meters (9' 10")
0.2 µW/sq cm speed < 1 kmh
60 µW/sq cm speed >= 1 kmh, Forward Radar
30 µW/sq cm speed >= 1 kmh, Side or Rear Radar
--------------------------------------------------
OUTSIDE U.S.
Europe 76-77 GHz
Japan 66 GHz.
Power Density in microwatts per square centimeter (µW/cm2)
Vehicle radars have also been known to operate at traffic radar frequencies in X and K bands, as well as at 35, 60, and 86 GHz. Some systems use ultra wide band (UWB) modulation, an advanced spread spectrum technique. UWB radars must transmit above 24.075 GHz (FCC regulations, Oct 2003).
The Environmental Research Institute of Michigan (ERIM) and TRW have developed (1998) a data base of radar cross-section measurements (radar target size) for situations and at angles pertinent to forward-looking vehicle radar (collision avoidance).
NCC應不會比FCC嚴格???

不用打電話問官員
直接上FCC官網搜尋
要什麼都有
OET -- FCC ID Search
Blind Spot Assist
Radar Sensor
24 GHZ
應該錯不了...
等
NCC 官員睡完午覺
真相就大白了
