Angular calibration of radar antenna system is composed of the calibration of angular error sensitivities ( also called directional sensitivity ), adjustment of cross - coupling of azimuth and elevation signals, and the calibrations of system errors such as antenna axial system error, dynamic delay and so on
雷達系統天線的角度標校包括對系統角誤差靈敏度（又稱定向靈敏度）的標定、方位俯仰信號交叉耦合的調整以及對天線軸系誤差、動態滯后等系統誤差的標定。 -
Based on the guidemode characters of dark spatial soliton waveguides and the theory of coupling between two waveguides, a kind of steerable all - optical directional coupler using dark spatial soliton waveguides is suggested
摘要基於空間暗光孤子誘導波導的模式特性以及光波在波導間耦合理論，提出了一種實現光控可變定向耦合器的方法。 -
Nonlinear directional coupler ( nldc ) is a switch used in optical network. w. s. man had studied transmission controlling with ground state soliton through nldc, it is obviously not available to used in superhigh speed network ; and mary j. potasek had studied the self - coupling with ultrashort solitons in nldc, self - coupling is difficult to control the signal transmitting. i has studied the transmission controlling with ultrashort solitons ( < 100fs ) in nldc, similarly i use a controlling pulse to control the signal pulse, it is the intensity of controlling pulse to decide the signal change its direction or not
非線性定向耦合器（ nldc ）是用在光網路中的光開關器件，它主要用在全光網路中， w . s . man等研究過基態孤子在nldc中的傳輸控制，便於對全光網路中數據的正確傳輸，由於目前研究集中在100fs的超短脈沖傳輸特性上，顯然基態孤子的特點不再適用於超高速網路； maryj . potasek等就超短脈沖在nldc中的自耦合做了研究，在光網路中自耦合任意性太大，不利於控制脈沖的傳輸。 -
In the paper, some factors are studied such as ratio of soliton and signal wavelength, linear refractive - index of media and coupling length which have influence on the performance of the steerable all - optical directional coupler
研究了孤子波和信號光波長之比、器件長度及介質的線性折射率對光控可變定向耦合器性能的影響。 -
This paper mainly studies the coupling error caused by induction voltage phase difference, and fluctuation of directional sensitivity caused by changes in near - field difference slope. the trend of system sum and difference phase difference, directional sensitivity and cross - coupling with change in distance is compared and discussed when the antenna is in the near - field and at a certain elevation
本文著重研究了因近場感應電壓相位差引起的耦合誤差，以及近場天線差斜率變化引起的定向靈敏度的變化；討論了天線在近場並有一定仰角的條件下，隨著距離的變化，系統和、差相位差、定向靈敏度與交叉耦合的變化趨勢。
