This chapter provides some numerical examples of measure of propagation velocity based on the diffraction curves. The real ground penetrating radar (GPR) pulses cannot have zero duration, because the band of the system (in particular the band of the antennas) is never infinite. In the real word, the diffraction curves have some "thickness," and this constitutes an unavoidable source of uncertainty, both with regard to the propagation velocity of the waves and with regard to the depth of the buried targets. The chapter describes some examples about the needed spatial step, frequency step and the correlated achievable horizontal and vertical resolutions. It shows some examples regarding the effect of the height of the observation domain and background removal. The chapter demonstrates application of 2D and 3D migration algorithms to field data

Abstract
This chapter provides some numerical examples of measure of propagation velocity based on the diffraction curves. The real ground penetrating radar (GPR) pulses cannot have zero duration, because the band of the system (in particular the band of the antennas) is never infinite. In the real word, the diffraction curves have some "thickness," and this constitutes an unavoidable source of uncertainty, both with regard to the propagation velocity of the waves and with regard to the depth of the buried targets. The chapter describes some examples about the needed spatial step, frequency step and the correlated achievable horizontal and vertical resolutions. It shows some examples regarding the effect of the height of the observation domain and background removal. The chapter demonstrates application of 2D and 3D migration algorithms to field dataI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
