遙測信號化 的英文怎麼說
中文拼音 [yáocèxìnháohuà]
遙測信號化
英文
telesignalisation-
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。The polarimetric sar is a new type imaging radar to measure polarimetric characteristic of radiant signals and combines both advantage of measuring full complex scattering matrix for each resolution cell in a scene and producing two - dimensional high resolution images, which greatly improve its ability to discern surface features. polarimetric sar is thus playing a more and more important role in research on remote sensing and application area
極化合成孔徑雷達（ polarimetricsar ）是用來測量輻射信號極化特徵的新型成像雷達，具有能夠測量場景中每個分辨單元的全極化散射矩陣和產生二維高解析度圖像的兩大優點，大大提高了它對地物的識別能力，因此在遙感技術研究與應用領域中起著越來越重要的作用。Research on retrieval of gps water vapor and method of rainfall forecast are keen field which draws all attention from wide world. the dissertation is accomplished on the basis of sino - italy collaborative project - ' the integral system of flood risk programming, monitoring and real time forecasting " and the primary achievements and conclusion reached include : ( 1 ) a reasonable design has been made for gps water vapor monitoring network according to the theory of gps satellite signal propagation and vertical distribution of water vapor and local synoptic characteristic of binjiang basin, the effective area where water vapor can be detected by gps station has been determined under different cut - off angles. the conclusion has been reached that 3 ~ 4 gps receivers are enough for water vapor monitoring in binjiang basin
Gps水汽反演和降雨預報研究是當前氣象遙感應用的一個前沿探索領域，本論文依託于中意科技合作項目「洪水風險規劃、監測和實時預報的集成系統」 ，主要成果體現在以下方面： （ 1 ）提出了一個合理的gps水汽監測網設計方案根據gps衛星信號傳播原理和水汽垂直分佈規律以及流域天氣的地方性特徵，確定了不同高度截角下一個gps站所能測定大氣水汽含量的有效范圍，得出了濱江流域只需要3 4個gps接收機就足以反映流域水汽變化的結論。
