receiver aperture 中文意思是什麼

receiver aperture 解釋
接收天線孔徑
  • receiver : n 1 接受者。2 收稅人，收稅官。3 招待人。4 窩家，收買賊贓的人。5 應戰者。6 【法律】破產案產業管理...
  • aperture : n. 1. 孔，隙縫。2. （照相機的）光圈；孔徑，口徑。
  1. The parameters that influence the single photon acquisition probability are the transmitter ' s tracking - pointing error, the far - field divergence angle, the link distance between transmitter and receiver and the receiver ' s antenna aperture

    得到影響單光子捕獲概率的主要參量是發射機的跟瞄誤差、光束遠場發散角、發射機和接收機的鏈路距離和接收機天線孔徑。
  2. Very small aperture antenna terminal vsat equipment has been installed at the hong kong observatory and chek lap kok for reception of the wafc london broadcast. the vsat equipment occupies very small space. it consists of an antenna and a receiver for reception of the satellite data stream and a data processing workstation for processing and display of the wafs information to forecasters and for incorporation into flight documents

    天文臺在總部及赤角分別安裝了甚小天線地面站vsat ，以接收倫敦世界航空區域預報中心的廣播，這套儀器佔地甚小，包括天線及接收器，用以接收人造衛星數據，也包括數據處理工作站，用以處理並顯示世界區域預報系統的資料，讓航空預報員參考及用以製作飛行氣象文件。
  3. At the same time, the " stop - hop - stop " approximation is no longer valid in sas due to the low speed of sound. the receiver has unavoidable movement, when echoes get to receiver from different distances. in order to overcome the problem, an image forming algorithm of multi - aperture sas is presented in the thesis, which is suitable for the case of non - " stop - hop - stop "

    為了解決測距、測速模糊問題， sas通常採用多子陣技術，而且由於sas 「停?走?停」假設往往不再有效，即測繪帶內不同距離回波到達基陣時，基陣存在不可忽略的運動，所以論文提出了一種「停?走?停」假設不成立條件下的多子陣合成孔徑聲納逐點成像演算法以得到相位保真度更高的復圖像。
  4. ( 1 ). here we build the system space geometry model : the transmitter and receiver fly on different platforms and at different height, two flight paths are unparallel. based on the chirp signal and the taylor series, we analyze the range history and synthetic aperture time, then demonstrate the equation of the azimuth resolution about air - born bistatic spotlight synthetic aperture radar, meanwhile we obtain the equations of doppler bandwidth and doppler frequency modulate rate

    本文以機載聚束式合成孔徑雷達成像作為研究背景，主要完成了以下幾方面的工作: （ 1 ）建立了一種機載雙站聚束式sar空間幾何數學模型，對方位分辨力進行了理論分析，進行了數值分析與模擬，討論了不同條件對雙站聚束模式sar系統分辨力的影響。
