摘要：

We developed an interferometric borehole radar system, which has one transmitter and two receivers. A new analog optical link is equipped in this new borehole radar system. Field experiments were carried out and the system was evaluated. Clear reflections from subsurface fractures were observed. Two radar profiles can be obtained by one measurement. These two radar profiles are acquired by two receivers spacing 1 m apart, therefore these profiles can be used for interferometry. The difference in these profiles is caused only from the different of the wave paths from the radar target. By interferometric interpretation, much detailed information can be obtained from borehole radar compared to the conventional technique. For example, the direct coupling component of the received signal can be used for electromagnetic well logging.
