摘要： 钻孔雷达是探地雷达的一种。传统的钻孔雷达可以确定目标地质体的深度，却无法判定目标地质体的精确方位；定向钻孔雷达不仅可以确定目标地质体的深度，还可以精确地确定目标地质体的方位。本文研究的定向钻孔雷达包括1个发射天线和4个接收天线。本研究通过增加移动窗口，进行窗口内的方位识别计算来实现残差法的改进。传统的残差法只能对一个目标进行方位识别；改进后的残差法可对井眼周围任意多个目标进行方位识别，并且利用4个接收天线所接收到波形的不同来确定目标地质体的精确方位，并开发了三维成像算法。最终利用模型得到合成数据，求得方位角，结合方位角进行三维成像，三维成像结果中井眼的正东方向和正南方向都有一个明显的异常，与原模型吻合良好。

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
