polarization fading 中文意思是什麼
-
Polarization diversity and maximum ratio combining ( mrc ) is used to restrain the sharp signal fading in the telemetry systems, in which the object is in flight at a high speed and rotating and in low elevation
在信號極化衰弱現象嚴重的環境中對快速飛行目標、低仰角運動目標以及旋轉運動目標等進行遙測接收時，極化分集最大比合成技術可以有效的改善接收性能。 -
In this thesis we analyze in detail the influence, created by random change of the optical wave polarization, on the output of the interferometer. then several principles of eliminating polarization - induced fading are introduced, and the principle that inserting two faraday rotator mirrors into the end of michelson fiber interferometer to eliminate the fading is analyzed in detail. this method can eliminate polarization - induced fading without additional signal processing, and make the output of the sensor stable
其中，本文詳細分析了光波偏振態的隨機漂移對干涉儀輸出的影響，介紹了目前幾種消偏振衰落技術的原理，著重討論了在光纖michelson干涉儀末端加兩個法拉第旋轉鏡的消偏振衰落的原理，該方法不需要任何附加的信號處理就可以消除偏振衰落，使干涉儀輸出穩定。
