  1. The work presented in this paper is carrying out to the theory research of dbf. the work includes : research of dbf algorithms, dbf antenna system composition and realization. the application of dbf algorithms used in high frequency ground wave radar for near ocean inspection and ocean situation remote sensor is also presented. at last, we give a effective scheme to implement broad - band constant beamwidth digital beam - former

    本文的主要工作是圍繞數字波束形成技術的理論研究,內容包括:數字波束形成演算法的研究,數字波束形成天線的系統構成和實現,以及將數字波束形成演算法應用於高頻地波雷達近海監測和海態遙感,最後給出了一種寬帶恆定束寬數字波束形成器的設計方案。
  2. The impedance match must be extremely good because at the frequency that the antenna beam ~ vork on the broad - side position, the reflcctions from all the bends add in phase to produce a large input vswr. in addition, a poor design of thc bends leads to high - power breakdown

    慢波線中使用了大量的波導e面180彎頭,系統對其駐波特性提出極高的要求,文中用高頻模擬軟體( hfss )優化設計了波導e面180彎頭。
