By analyzing the feature of short pulse used in short-pulse ground penetrating radar, the method of pulse generating is presented. The basic structure of pulse generating circuit involves avalanche transistor, step recovery diode and transmissions line. In order to analysis and operate the circuit, some methods and principle are given in the paper, Measured results confirm the design is versatile and may be used in the ground penetrating radar system. Some traits have been demonstrated by experiment, as follows: high amplitude, short pulse duration time, good symmetry and low distortion.

“…However, this method has a long development time and high design cost because some of the components are customized. Other off-the-shelf designs include avalanche transistors [ 10 ], tunnel diodes [ 11 ], nonlinear transmission lines (NLTLs) [ 12 ], photoconductive switches [ 13 ], bipolar transistors [ 14 ], field effect transistors (FETs) [ 15 ], and SRDs [ 16 – 24 ].…”

Because of the importance of ultra-wideband (UWB) radar in various applications, short pulse generation in UWB systems has attracted a lot of attention in recent years. In order to shorten the pulse, nonlinear transmission line (NLTL) is imported, which expands the application of step recovery diode (SRD) for pulse generation. Detailed analysis and equations for this SRD and NLTL-based pulse generation are provided and verified by simulation and experimental results. Factors that could cause pulse waveform distortions are also analyzed. The generator circuit presented in this paper generates 130ps and 3.3V pulse, which can be used in UWB radar systems that require sub-nanosecond pulses.

“…Moreover CPW-based NLTLs need no complex processes such as via holes and back-plating, which were needed by microstrip-based NLTLs and cause limited bandwidth (up to 40 GHz) and lower performances. [3,9] 2. Schottky diode structure design and model…”
