the technology of retrodirective array is very important to achieve this goal 而方向回溯天線技術是實現(xiàn)這一目標的一個極其重要的途徑。
but in our country, no researchers have studied retrodirective array synthetically and no correlative reports 但在國內(nèi),由于研究起步較晚,目前尚沒有學者對其進行綜合研究,鮮有相關報道。
at present, there are many articles about it in other countries . many forms of retrodirective arrays have been used for experimental study and all of them have good performance 目前國外已有很多文獻報道,多種形式的方向回溯天線陣用于試驗研究,并表現(xiàn)出良好的性能。
the dissertation mainly focuses on the design and realization of retrodirective array with a lot of theoretical, numerical methods and experimental studies, and also includes discussing various technology and theory about it . more attentions are paid to the engineering application 本篇論文從方向回溯實現(xiàn)的原理出發(fā),對各種方向回溯天線技術、理論進行了初步探討,從理論、數(shù)值方法以及實驗等方面著重研究了方向回溯天線的設計和實現(xiàn),注重面向工程應用。
firstly, a novel four-element retrodirective array is designed, based on dual-polarization microstrip array antenna technology and phase-conjugating mixers technology . secondly, a simple, effective testing system is designed and set up, by which the array ’ s monostatic and bistatic radar cross section ( rcs ) are tested 本文所采用的技術和方法,新穎、簡單、易實現(xiàn),適合具體的工程應用;本文的結果對于天線研發(fā)人員研究方向回溯天線有一定的參考意義。
