【摘要】 3D定向钻孔雷达系统能够对钻孔四周进行高精度三维成像,在单个钻孔中即可完成目标体距离、方位的探测,相对2D钻孔雷达具有探测精度高、速度快、深度大的优点。笔者对3D定向钻孔雷达系统的工作和成像原理、技术规格进行了详细说明,并结合现场数据说明了其实际应用效果。更多还原

【Abstract】 The 3D directional borehole radar system can perform 3D mapping for the surroundings of a borehole with high resolution.The detection of the distance from the borehole and the angle in relation to the magnetic North can be completed in a single borehole.The system has many advantages over the 2D borehole radar in such aspects as high resolution,rapidness and great penetrating depth.The authors deal with the working and imaging principles and technical specifications of the 3D directional borehole radar in details and,combined with field data,show its true application results.更多还原
