Abstract :
The input signal for ground penetrating radars (GPR) is as important as the radar hardware such as the antenna and the receiving unit. The pulse duration, peak value and pulse profile are the main time domain features of a pulse that have to be considered in GPR applications. The most popular pulse signal used in GPRs is the Gaussian pulse and in this paper its performance is compared with that of the differentiated Gaussian pulse. The clutter level and the scattered signal strength of the GPR response are assessed in the comparison.
