Signal processing in UWB radars of small distance

In the paper, the methods of signal processing with reference to ultrawide band (UWB) radars designed for detection and remote measuring parameters of moving objects at short ranges (tens of centimeters-several meters) are considered. It is shown that the relative changes of an oscillation frequency filling an outgoing pulse and duration of these pulses originating at reflection from a moving target are very small; that makes impossible their practical measurement. Therefore, for detection of signals reflected from a moving target the phase method is chosen.
