Fig. 4. Some raw data obtained from CMP surveys using GPRMAX2D with 450-MHz frequency: (A) dry ( ${epsilon}$ _r = 5) soil over wet ( ${epsilon}$ _r = 15) soil layer model, (B) wet ( ${epsilon}$ _r = 15) soil over dry ( ${epsilon}$ _r = 5) soil layer model. The stars give locations of ground wave peaks used to determine the velocity.
