Description
測をする形式であるが、方位切替えは電子的切替であるから高速切替えが可能である。
εγ=2−(r/R)2
R:球の半径
r:球の中心からの距離
なお、誘電材料とは、常誘電性、強誘電性、若しくは反強誘電性を示し、かつ電気伝導性を有さない材料である。
ーダが提案された例はない。
前記電波レンズは、中心の球核の外側に異径球殻を順次積層して構成され、
前記電波レンズの比誘電率は、前記誘電材料の発泡倍率に加えて無機高誘電フィラーの添加割合を調整すると共に前記異径球殻の層数を調整することで風速レーダに適合させており、
観測すべき所望の複数の方位角方向に電波レンズを介して送、受信される電波の焦点位置に一次放射器を配設し、さらに、前記一次放射器を支持する複数の支持レールを備え、前記複数の支持レールは、互いに直交して設けられており、前記一次放射器を天頂方向、及び互いに直交する支持レール上に配設した風速レーダとしたのである。
ている球形の電波レンズであり、これを支持部材2で支持している。支持部材2は電波レンズ1の直径Rより若干小さい径の環状支持板2a内に電波レンズ1を受け、環状支持板を支持脚材2bで支持している。電波レンズ1の下方には所望の観測方向に対応する複数の一次放射器3(図示の例では3H 、3N 、3S 、3E 、3W の5個)が固定配置されている。これら一次放射器3は、支持軸4に支持された支持レール5a、5b上に支持されている。6はレドーム、8はケーシング、10は送、受信器、制御装置等を収納した制御ボックスである。
観測できる。即ち、送信器11から送り出され、一次放射器3の1つから所定方向(図示の例では南)(3S )の天頂角θに向けて電波レンズ1を経てパルス状の電波が放射されると、この電波は上空で大気の乱れ(乱流)に伴う屈折率の揺らぎにより僅かであるが散乱され、高度に対応する時間遅延を伴って電波レンズ1へ戻る。従って、散乱波強度を時間の関数として測定することにより高度別のデータを得ることができる。このような測定は受信器12で受信した電波信号を制御ボックス10内で演算することにより得られる。
西南北とそれぞれ天頂角θをなす位置に停止させ、それぞれの位置で風速、風向のデータを測定する点が異なる。
なお、図3、図4、図6、図7は、いずれも参考形態である。
