High magnitude, narrow pulse time domain pulse signal sources and ultra-wide band, low later-time ring time domain pulse antennas are the important components of the pulse ground-penetrating radar. In this paper, the electro-magnetic interference can be decreased by using ducking technology. High amplitude time domain pulse signal sources with 156.2V pulse amplitude, 1. 6ns pulse width are designed. Besides this, a novel UWB time domain pulse antenna with semi-circle arms has been proposed. Compared to the traditional bow-tie antenna with triangular arms, the VSWR of the UWB time domain pulse antenna is less than 3.5 from 0. 5GHz to 7GHz. And the later-time ring decreased from 17.5% to 8.3%. Lastly, an experiment for detecting the buried targets is carried out using the integrated radar system, the experiment demonstrated high resolution ratio especially for shallow targets. Superior performances and huge value of the pulse ground-penetrating radar front-end detecting subsystem designed in this thesis have been further verified.
