As the vital development of the millimeter wave guidance technology, phased array antennas use electrical control scanning beam, which results to faster scanning velocity, more flexible beam control and higher anti - interference ability. thus it can realize target seeking, tracing, guidance at the same time, and can work in the complex and worsening condition
作為毫米波制導技術的一個重要發展方向,相控陣制導技術中的相控陣天線是採用電控方式掃描波束,掃描速度快、波束控制靈活、抗干擾能力強等,可以同時完成目標搜索、跟蹤、引導等多項功能,能工作在日益復雜和惡化的工作環境中。Parabolic antenna in a widely used is tracking antenna area, by use the optimum design, it may produce a very narrow beam, it ' s tracking precision is high, but because it ' s beam width is very narrow, the searching target is very difficult
摘要拋物面天線是火控雷達中普遍使用的一種跟蹤天線,通過系統優化設計,可以形成很窄的波束,所以其跟蹤精度很高,因為其波束很窄,所以搜索發現目標困難。Tpvm is a kind of random phase feeding method, which imports noise an d decreases the accuracy greatly. the effects of scpfm and sccpfm are better, especially the latter
二可能值法是一種隨機饋相法,引入了噪聲,反而使相控陣天線的波束指向精度大為降低。The key for phased array antennas with good functions is the use of controllable phase shifters. however, phase quantization errors affect the accuracy of phased array antenna beam pointing badly, which is mainly researched here
其中可控數字移相器的使用,是相控陣天線優越性能實現的關鍵,但由此引入的相位量化誤差,嚴重影響了相控陣天線的波束指向精度。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。According to the reciprocal characteristic of dual - mcde reciprocal ferrite phase shifters, the antenna only requires to provide the sa : lle beams of operation between the trtinsmit and receive beams. in addition, 1he phased shifter can operate in various polarizations such as linear polarization or circular polarization, which is adiipted to the development of modern ra ( 1ar technologies
對電掃描相控陣天線來說,雙模互易式鐵氧體移相器的互易特性可使收、發在同一特定波束位置上工作;此外,雙模互易鐵氧體移相器可以在線極化、圓極化等多種極化方式下工作,適應了現代雷達技術的發展。The radiation orientation of tow - dimensional phased arrays byusing the method of two probable numbers is investigated, and an effective formulation for such an investigation is presented in this paper
研究了二可能值法對二維相控陣天線波束指向的影響,並推導出有效實用的理論公式。So their method can be used not only for phased array radar but also for reflector antenna radar. their research shows the ? a - stap can provide good clutter - suppression performance and has many advantages
所以基於和、差波束的空時二維處理方法不僅可以用於相控陣天線雷達,也可以用於一般的反射面天線雷達。Their interest in ? a - stap stemmed from the fact that antenna engineers have excelled in the design of high performance sum and difference beam whether for phased array or for reflector antenna
人們對這種特殊的空時二維處理感興趣的原因是無論相控陣天線系統還是反射面天線系統,天線工程師都可以設計出性能很好的和、差波束。Phased array radar is a detective system with multiple function, high reliability and adaptive ability, spatially the rapid scan and beam shape change characteristic of phased array antenna made its application more and more abroad
相控陣雷達是一種具有多功能、高可靠性和自適應能力的探測系統,尤其是相控陣天線所具有的波束快速掃描能力和波束形狀快速變化能力等優點,使得相控陣雷達得到了越來越廣泛的應用。Abstract : the radiation orientation of tow - dimensional phased arrays by using the method of two probable numbers is investigated, and an effective formulation for such an investigation is presented in this paper
