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。
in chapter 6, the retrodirective ability of the electrically small antennas with two ports has been studied 第六章對多饋電一體化天線用于方向回溯的可能性進(jìn)行了仿真研究。
the gain of the retrodirective antenna in the incoming signal direction fluctuates with ? db as the incident angle increases 在來波方向上,天線系統(tǒng)的增益隨來波的入射角有fzdb的波動。
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(xué)者對其進(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。
