the technology of retrodirective array is very important to achieve this goal 而方向回溯天線技術(shù)是實(shí)現(xiàn)這一目標(biāo)的一個(gè)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(guó)內(nèi),由于研究起步較晚,目前尚沒有學(xué)者對(duì)其進(jìn)行綜合研究,鮮有相關(guān)報(bào)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(guó)外已有很多文獻(xiàn)報(bào)道,多種形式的方向回溯天線陣用于試驗(yàn)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(shí)現(xiàn)的原理出發(fā),對(duì)各種方向回溯天線技術(shù)、理論進(jìn)行了初步探討,從理論、數(shù)值方法以及實(shí)驗(yàn)等方面著重研究了方向回溯天線的設(shè)計(jì)和實(shí)現(xiàn),注重面向工程應(yīng)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(shù)和方法,新穎、簡(jiǎn)單、易實(shí)現(xiàn),適合具體的工程應(yīng)用;本文的結(jié)果對(duì)于天線研發(fā)人員研究方向回溯天線有一定的參考意義。
