" with the developme1lt of the phased array antenna system , it is very important to research on various phase shifters , particularly on a duai - mode latching reciprojal ferrite phase shifter 隨著相控陣雷達技術的應用發展,各類移相器的研制工作越來越重要,其中雙?;ヒ阻F氧體移相器由于其獨特的優點而得到廣泛應用。
In this thesis , the overall scheme is to establish a circular array system which is formed from units of parabolic antenna . then , the resultant field will be detailed studied , in order to find out a steady - going array antenna system with the best combined efficiency 本文的主要內容是,利用拋物反射面天線組成圓形陣列,并對該天線陣列的空間合成場問題進行研究,力求在實際應用中得到穩定的、合成效率達到最優的空間合成場。
With compensation of signal ’ s time delay from different radiating element by phase shifters , phased - array antenna can control array beam easily . because there are no mechanical devices for rotating beam , the phased - array antenna system can scan everywhere in beam covered areas in millisecand by stepping the phase shifters . it improves the tracking velocity of antenna towards the object , and becomes the development trends of weapon system antennas 相控陣天線利用移相器補償信號到達輻射單元時間的差異,從而控制波束方向;天線沒有機械旋轉問題,只需改變移相器的設定值,波束便可以在毫秒級內掃描其覆蓋空域內的任何地方,提高了天線對目標的跟蹤速度,是目前武器系統天線的發展方向。
