To allow directions of variation of the electric field vector of horizontally polarized waves radiated to an observation target to be fixed at a right angle to a specific plane.SOLUTION: An oriented direction of an aerial 201 is adjusted so that an azimuth direction Az coincides with the normal direction of a specified plane, a beam is radiated in the oriented direction of the aerial 201, and a beam reflected by an observation target is received using the aerial 201. The specified plane is a plane formed by a relative direction of the aerial 201 to the observation target 102 and the normal direction N of the target plane at the location of the observation target 102, or a plane obtained by rotating, around the normal direction N of the target plane at the location of the observation target 102, the plane formed by the relative direction of the aerial 201 to the observation target 102 and the normal direction N of the target plane at the location of the observation target 102.SELECTED DRAWING: Figure 1

    【課題】観測対象に照射される水平偏波の電場ベクトルの変動方向を特定平面に対して直角に固定できるようにする。【解決手段】アジマス方向Azが特定平面の法線方向と一致するように空中線201の指向方向を調整し、空中線201の前記指向方向へビームを照射し、観測対象に反射したビームを空中線201を使って受信する。前記特定平面は、観測対象102に対する空中線201の相対方向と、観測対象102の位置での対象平面の法線方向Nと、が形成する平面、または、観測対象102に対する空中線201の相対方向と、観測対象102の位置での対象平面の法線方向Nと、が形成する平面を、観測対象102の位置での対象平面の法線方向N回りに回転した平面である。【選択図】図1
