1. An apparatus utilizing the profile of a travelled power spectrum of a received signal wave of pulses transmitted through or reflected in an object, corresponding to an originally incident pulse having a predetermined power spectrum, to measure the characteristics of said object, said apparatus comprising:

  • processing means for reducing the scalloping of the travelled power spectrum of said received signal wave;

    recovery means for deriving the travelled power spectrum with the reduced scalloping; and

    extracting means for extracting information on the characteristics of said object from the derived power spectrum.
