When measuring a radiation pattern of an antenna in a radio wave reflection environment, it is difficult to measure the radiation pattern with high accuracy due to the influence of multiple paths. The present invention is provided with: an aerial moving body (3) that moves or is stationary over the sky of a measured antenna (30) that radiates radio waves (2) in the sky direction; and a position measurement unit (51) that is provided on the ground and measures the position of the aerial moving body. A measurement antenna (14) for receiving radio waves (2) and a radio wave measurement unit (15) for measuring received radio wave data (73) including at least one of the amplitude and the phase of the radio waves (2) received by the measurement antenna (14) are mounted in an aerial moving body (3). The device is further provided with a radiated radio wave data generation unit (21) that generates radiated radio wave data (71) that includes the received radio wave data (73) and radio wave source relative position data (78) that indicates measurement point data (74), which is the position of the aerial moving body (3) at the time when the received radio wave data (73) is measured, as the relative position with respect to the antenna to be measured (30).

    在电波反射的环境下测定天线的辐射方向图的情况下,因多路径的影响而难以以较高的精度测定。本发明包括在向上空方向辐射电波(2)的被测量天线(30)的上空移动或静止的空中移动体(3)、及设置于地面上并测定空中移动体的位置的位置测定部(51)。空中移动体(3)中搭载有接收电波(2)的测量用天线(14)、及测量包含测量用天线(14)接收的电波(2)的振幅和相位中的至少某一个的接收电波数据(73)的电波测量部(15)。还包括辐射电波数据生成部(21),该辐射电波数据生成部(21)生成包含接收电波数据(73)、及将在测量出接收电波数据(73)的时刻空中移动体(3)的位置即测量点数据(74)作为相对于被测量天线(30)的相对位置而表示出的电波源相对位置数据(78)的辐射电波数据(71)。
