According to the principle of impulse GPR, the short pulse generator is an important basic circuit of GPR, it is an important part of radiation excitation and sampling circuit.
In this paper, we first obtain the FRFT of the uniform impulse-train sampled signals, and based on it, we deduce sampling theorem and reconstruction formula for bandpass and lowpass signals with FRFT.
