This software was designed as a processor of microwave reflectometer raw output data. The reflectometer measures the power of the reflected wave of a given sample in a wide frequency band. It provides the extraction of a complex-valued reflection coefficient from absolute-valued data utilizing the Fourier holography concept. This concept brings the following algorithm of data processing:

  1. Measure the power reflection coefficient of a given sample under investigation.
  2. Measure the power reflection coefficient of a given metal sheet placed at the same distance from the horn as the sample frontal plane.
  3. Transform both characteristics from the frequency domain to the time domain with discrete Fourier transform.
  4. Apply weight windows to the signals suppressing artifacts of reflection from horn throat and aperture, fastening tools, and other objects present in the laboratory.
  5. Transform both characteristics from the time domain to the frequency domain and divide one to the other. The complex-valued reflection coefficient is obtained as a result.
