Figure 2

Migration aperture () for the rms and the LLNL approximations as a function of (target depth). The antenna-medium distance is 10 cm, and the radar wave velocity into the medium is examined in the range from 8 to 20 cm/ns. The aperture is limited to the contributions affected by a phase error at the highest frequency (6 GHz) lower than .
