| Abstract(in English) | It is difficult to digitize directly the received signal of a subsurface radar because the radar signal contains very high frequencies. Then the sequential sampling circuit has been used to obtain the radar signal. However, this method reduces the SNR of the signal. In order to solve this problem, the Delayed Positive Feedback Amplifier (DPFA) has been proposed here. It is possible to improve the SNR of a radar signal. The DPFA was made successfully and applied to a subsurface radar. Experimental results have verified the effects of the DPFA. |
