要約
(EN)
When each radio wave independently emitted from each scatterer antenna (50-n) is respectively received using a receiving antenna for calibration (60a), a computer (10) measures the amplitude and phase of each received signal (S60a), with a transmitted signal (S22a) used as a reference signal, decides the target amplitude on the basis of each amplitude measured, and decides the target phase on the basis of each phase measured. The reference attenuation amount control voltage (VAa-n) for each attenuator (14a-n) is set to each attenuation amount control voltage for bringing each measured amplitude into agreement with the same target phase respectively, and the reference phase shift amount control voltage (VPa-n) for each phase shifter is set to the phase shift control voltage for bringing each measured phase into agreement with the same target phase respectively.

(ZH)

计算机(10)以发送信号(S22a)为基准,对使用校正用接收天线(60a)分别接收各散射体天线(50-n)单独放射的各电波时的各接收信号(S60a)的振幅和相位分别进行测定,根据分别测定的振幅来决定目标振幅并且根据分别测定的相位来决定目标相位。各衰减器(14a-n)的基准衰减量控制电压(VAa-n)被设定为用于分别使各测定的振幅与同一目标振幅一致的各衰减量控制电压,各移相器(13a-n)的基准移相量控制电压(VPa-n)被设定为用于分别使各测定的相位与同一目标相位一致的移相量控制电压。
