Example text

During averaging process, the media boundary reflected signals remain in the subtrahend signal, so further subtraction of the averaged signal from the signals of the entire profile leads to the situation when reflections are removed and information about these layers will be lost. Thus the background removal process outwardly improves the radar image, but at the same time it introduces distortions in the information contained in the profile by removing the useful information about layers, and can add to the signals corresponding to nonexistent objects.

In addition to the cepstral data processing, using the well-known methods of inverse filtering and deconvolution could solve a similar problem. However, in all cases the high requirements of noise and measurement accuracy of waveforms remain unchanged for the achievement of high precision measurements of the boundaries coordinates. Using the reflected signal waveform for probing and analyzing the return for the frequency content could significantly improve the accuracy of radar measurements. However this means the UWB radar must have very high power signal, a wide dynamic range and a receiver capable of accurately recording the signal waveform for further analysis.
