At last , a project of direction - finding system is presented 文章最后提出了一個(gè)測(cè)向定位系統(tǒng)方案。
This paper is worked to solve the phase center of the directional antenna , accordingly to giving some references for the interception and direction - finding system 本文是為了解決定向天線的相位中心問(wèn)題,為偵測(cè)合一系統(tǒng)設(shè)計(jì)提供參考而展開(kāi)研究的。
A new automatic direction - finding system to monitor radio channels and locate sources of interference in and around hong kong was installed in the radio monitoring unit of ofta 電訊局無(wú)線電監(jiān)察組裝設(shè)全新自動(dòng)測(cè)向系統(tǒng),以監(jiān)察無(wú)線電頻道及找出本港境內(nèi)或附近的干擾來(lái)源。
In the interception and direction - finding system , the phase center of the antenna is very important to the direction - finding , however , the phase center of directional antenna is few studied in the home and overseas 在偵測(cè)合一系統(tǒng)中,天線系統(tǒng)的相位中心對(duì)于系統(tǒng)測(cè)向有著至關(guān)重要的作用,但是目前國(guó)內(nèi)外對(duì)于定向天線的相位中心研究的非常少。
