A New Short Pulse Generator for Ground Penetrating Radar
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.
