  • Patent number: 10746765
    Abstract: A data processing method and a measurement device is provided in which an electromagnetic wave radiates toward an object to be measured and measurement data obtained by measuring reflected wave of the electromagnetic wave reflected from the object to be measured is processed. First processing data S(kx, ky, ?) is acquired by performing discrete Fourier transform (DFT) relating to an x-coordinate component and a y-coordinate component on measurement data s(x?, y?, ?). Then, an angular frequency ? is converted into a kz component after extending a range from which a ky component can vary, thereby calculating second processing data S?(kx, ky, kz). Then, the second processing data is subjected to inverse Fourier transform to calculate data f(x, y, z) of reflexibility of the object to be measured. In the extension of the ky component, local maximum value processing and a process of suppressing generation of an aliasing component using a ratio are performed.
