B: Dead Zone Target Group
C: Vertical Distance Target Group
D: Horizontal Distance Target Group

The detail introduction of 11 target groups is as following:
1. A1-A5: Axial-Lateral Resolution Target String Group,
The distances between the Lateral branch of the groups and the acoustic window are 30mm, 50mm,
70mm, 120mm and 160mm respectively. Group A1 and A2 have the adjacent target horizontal
interval 1mm, 5mm, 4mm, 3mm, 2mm from left to right sequence. Groups A3-A5 are 5mm, 4mm,
3mm, 2mm. The vertical target string branch has the adjacent target vertical interval 4mm, 3mm,
2mm, 1 mm from up to down sequence for all groups of this series.
2. B: Dead Zone Target Group,
The adjacent target string lateral intervals are 10mm. The distance of the target strings to the
acoustic window are respectively 10mm, 9mm, 8mm, 7mm, 6mm, 5mm, 4mm, 3mm.
