4 . proposing several kinds of vertical patterns and bank protection patterns 提出了城市濱水區(qū)綠地生態(tài)空間構(gòu)建的幾種豎向模式和護(hù)岸模式。
The ground screen is utilized to obtain enhanced mirror affect , yet due to the disequilibrium of the electricity feeding , the coupling loses balance , which results in a shift of zero point of the vertical pattern 地網(wǎng)的作用是使地面能夠起到更好的鏡像作用,但是由于線性陣列相對于地網(wǎng)結(jié)構(gòu)而言饋電不均衡,導(dǎo)致了耦合的不均衡,結(jié)果是使得線性陣列的垂直面方向圖零點(diǎn)產(chǎn)生了偏移。
The synthesis method could cancel the ionosphere clutter efficiently . lastly , a kind of linear array composed by circular array is designed ; the max directivity synthesis method under condition of vertical pattern zero point 最后,本文設(shè)計了一種由圓陣列構(gòu)成的線性陣列,對于單個圓陣列使用垂直面的零點(diǎn)約束和效率約束下的最大方向性綜合方法,對于整個陣列,我們在水平面控制陣列的零點(diǎn)。
Secondly , the dissertations gives two array synthesis methods with aspect to circular array to cancel the ionosphere clutter , one is the circular max directivity synthesis method under condition of vertical pattern zero point restriction , the other is the circular max directivity synthesis method under condition of vertical pattern zero point restriction and efficiency restriction 然后為了對消電離層干擾,本文給出了兩種圓陣列最大方向性綜合方法,第一種是在垂直面方向圖零點(diǎn)約束下的綜合方法,第二種是在垂直面零點(diǎn)約束和效率約束下的綜合方法。
