  1. Single beam focusing lens antenna is the basis and crux of the multiple beam focusing horn lens antenna. only adequately and accurately analyzing focal area ’ s position and resolution, consider the influence when horn feed ’ s position is displaced to different location, we can design multiple beam focusing horn lens antenna

    單波束點聚焦透鏡天線是多波束聚焦透鏡天線的基礎和關鍵，只有充分精確地分析了單波束點聚焦透鏡天線解析度大小和焦斑位置，以及單個波束的偏移產生的相應影響，才能設計多波束聚焦透鏡天線。
  2. Beam deflection produces boresight error ( bse ) which is defined as angle shift between viewing direction and true direction. boresight error slope ( bses ) is defined as the ratio of angle shift to the tracing angle of the antenna

    波束偏移的主要後果是產生瞄準誤差，使目標的視在位置與真實位置有一個角度差，這個角度差就是天線罩的瞄準誤差。
  3. Beam deviation loss

    波束偏移損耗
  4. Radome is designed to protect the antennas from the external environment. however, radome is interfering with the electromagnetic radiation of antenna, which may result in significant degradation of antenna performance, cause transmission attenuation and beam deflection

    天線罩在保護天線不受外界影響的同時對天線的電磁輻射產生某些干擾，使天線的電性能降低，引起天線的傳輸損耗和波束偏移。
  5. The previous discussion addressed the theory required to compute the relative phase shift between adjacent radiating elements in order to position the beam of an array - type antenna to a specific angle off of the antenna boresight axis

    前面的討論中給出了計算使陣列天線的波束相對天線視軸線偏移一個給定角度所需的相鄰單元間相對相移的理論。
  6. We discuss the effect on the focusing of the probe beams for the five initial parameters : the amplitude of the pump beam, the separation between the pump and the probe beam centers, the wavelength ratio of the pump and the probe beams and the ratio of the initial beam widths at the directions of x and y. our numerical results show that, more the amplitude of the pump beam, the wavelength ratio of the pump and the probe beams and the ratio of the initial beam widths at the direction of y, more the probe focus ; the separation between the pump and the probe beam centers and the ratio of the initial beam widths at the direction of x have optimum values, respectively

    研究了泵浦光束輸入振幅、泵浦光束-信號光束初始偏移、泵浦光束-信號光束波長比和泵浦光束-信號光束x 、 y方向的初始束寬比五個參量對信號光束聚焦程度的影響。數值模擬結果表明，泵浦光束輸入振幅越大、泵浦光束-信號光束波長比越大、 y方向束寬比越大，信號光束聚焦程度越大；泵浦光束-信號光束初始偏移和x方向初始束寬比都存在一個最佳值，使得光束聚焦達到最佳效果，有趣的是這兩個最佳值的比值基本保持不變約為0 . 4 0 . 6 。
