Reconstruction results of ultrasonic laboratory data using the conventional imaging method. Reconstruction results using real acoustical measurements and the conventional imaging technique as well as the regular along-track scheme with increasing values (a-c) of the platform speed. (a)${\Delta }^{\text{A}}={\Delta }_{\text{max}}^{\text{A}}$, v=0.05 m/s. (b)${\Delta }^{\text{A}}=2{\Delta }_{\text{max}}^{\text{A}}$, v=0.1 m/s. (c)${\Delta }^{\text{A}}=3{\Delta }_{\text{max}}^{\text{A}}$, v=0.15 m/s.
