  • : 動詞1. (引導) lead; guide 2. (傳導) transmit; conduct 3. (開導) instruct; teach; give guidance to
  • : 通量詞(用於動作)
  • 波導 : [物理學] (用在微波波段傳輸電磁波的裝置) waveguide; duct
  • 通信 : communication; communicate by letter; correspond
  1. Because of radio wave propagating along the ducts with enhanced fields on the order of the free - space field, the problems of the co - channel interference are more complicate for communication systems with the results of intersystem interference and the formation of other system, and therefore affecting the determination of the coordination distances or the optimization of the distribution and separation of delay, and for surveillance system such as radar system the problems can be radar holes or the extensions of detect range

    對于電路,它使系統間的相互干擾問題變得復雜,既可能幹擾其他系統又可能形成另外的系統,從而影響系統的有關參數如中繼電路的最佳組合(分佈、間隔)和協調離,對于探測系統產生的則是雷達空洞、超視探測等問題。這些問題對相關線電系統特別是軍事應用系統可能是致命的,因而以傳播為代表的反常傳播特性研究受到極大重視。
  2. Case 1 : when there is no relative measurement, each satellite uses its own on - board attitude sensors to determine its attitude, and exchange the information through the communication link between formation satellites, and then the relative attitude is determined through simple mathematical operation. case 2 : based on the range measurements of gps like sensors, using two - point measurement of the relative orbit state to establish relative orbit and attitude kinematics and measuring equations. and state estimation is achieved through the extended kalman filter technology and unscented kalman filter technology, respectively

    方案一,在星間相對測量時,由衛星自身攜帶的姿態敏感器實現單星高精度姿態確定,利用星間鏈路進行息交互,過簡單的數學計算獲得星間相對姿態;方案二,利用類gps相對測量,建立了編隊衛星相對軌道運動和相對姿態運動模型及相對離測量方程,推了兩點相對軌道運動模型,設計了擴展卡爾曼濾器及uscented卡爾曼濾器,對相對位置、速度和姿態進行估計。
