Abstract: Borehole radar is a kind of ground penetrating radar (GPR). Conventional borehole radar can determine the depth of the geological body, but it's unable to determine the azimuth of geological target precisely. Directional borehole radar can determine not only the depth of the geological body, but also the orientation of the geologic body. In this paper, the directional borehole radar, consisting of one transmitting antenna and four receiving antennas, is applied to determine the positions of several targets by the modified residual algorithm through adding moving windows to the traditional residual algorithm. A three dimensional imaging method is discussed in this paper too. We used the model of synthetic data obtained with azimuth angle to realize 3D imaging, and 3D imaging results in the east and south direction of the well showed an obvious anomaly, which is in good agreement with the original model.

Key words: ground penetrating radar(GPR), borehole radar, residual algorithm, three dimensional imaging algorithm
