altitude azimuth 解釋
高度方位法
  • altitude : n. 1. 高，高度；海拔（高度）。2. 【天文學】地平緯度。3. 〈常 pl. 〉高處。4. 高位，高等。5. 【數學】頂垂線，高線。
  • azimuth : n. 1. 方位（角）。2. 【天文學】地平經度。
  1. In astronomical coordinates ( reference mark is north latitude 43. 9 ), analyzed is the effect of azimuth angular velocity, acceleration and altitude angular velocity, acceleration etc. some formulae were given to compute all correlative quantities. with regard to the course of data processing beforehand, the thesis focuses on outliers eliminating technology because of outlier increasing acutely of high - elevation tracking ( approaches 10 - 20 % )

    在觀測坐標系中推導出確定天頂盲區理論范圍公式和滿足過天項跟蹤條件的關系式；在天文坐標系中以長春衛星觀測站（北緯43 . 9 ）作為計算基準，分別討論了方位、俯仰方向的角速度、角加速度等對天頂盲區的影響，在理論分析上為解決過天頂跟蹤問題打下了基礎。
  2. Time and altitude azimuth

    時間高度求方位角法
  3. However, there is a fundamental limitation to the standard altitude - azimuth optoelectronic system

    然而地平式光測設備的缺陷是存在天頂盲區。
  4. At present mounts of optoelectronic measurement system have mainly two kinds of frame, i. e. altitude - azimuth form and equatorial form. the vast majority of large telescopes built are of an altitude - azimuth pedestal design in order to track fast moving satellites

    陸基型光學測量設備目前主要採用地平式和極軸式兩種結構模式，由於地平式系統成本低，軟硬體成熟度和工作可靠性高等原因，在觀測人造衛星的儀器中絕大部分採用地平式裝置。
  5. That is, the occasional situation where the object of interest passes directly overhead ( 90 zenith pass ). azimuth axis must rotate nearly 180 ? instantly. therefore, the standard two - axis altitude - azimuth pedestal will be unable to remain pointed at the object through the zenith pass event

    所謂天頂盲區問題是指目標過天頂時對地平式設備方位軸有一個極大的過載要求，需要方位軸瞬時調轉180 （或略小於180 ） ，此時方位變化的角速度和角加速度在數學意義上是無窮大，導致目標丟失。
  6. Through the analysis of the test data and the new development in the relevant literature, some more realistic models for sea - clutter and multipath propagation is concluded and the simulation is accomplished in the software. they provide the foundation for low - altitude radar target detection & tracking techniques research. in the second part, radar low - altitude target detection & parameters ( elevation - azimuth - range delay - doppler shift ) measure are studied

    （海）雜波和目標信號的多徑傳播嚴重影響了雷達低空目標探測與跟蹤的性能，通過分析國內外的有關試驗數據和最新的研究進展，總結出比較接近實際的海雜波和多徑傳播模型，並在有關軟體中實現了海雜波與多徑傳播的模擬，為進一步研究各種低空目標探測與跟蹤測量演算法提供了保證。
  7. Table of computed altitude and azimuth

    高度方位計算表
  8. The altitude / azimuth grid shows the positions of objects on a map relative to the observer ' s local horizon
