Abstract :
The signals of monostatic pulse radar in a water-filled borehole surrounded by horizontally layered rocks are numerically calculated using the finite-difference time-domain method (FDTD). In two cases of horizontally layered rocks, unwanted radar signals caused by interactions between borehole guided waves supported by the connection cable and horizontally layered rocks are calculated. Then, suppression of unwanted radar signal is analyzed here depending on the finite length of perfect magnetic conductor (PMC) coating along the connection cable of the radar.
