This Small Business Innovation Research (SBIR) Phase I project will demonstrate the feasibility of using magnetic tensor gradiometry to both locate and determine the depth of buried underground and/or submerged underwater ferrous pipes. Detection and location of subsurface pipes is of great importance to the utility, natural gas, and petroleum industries. Existing techniques such as Ground Penetrating Radar suffer from a number of limitations, including the inability to accurately scan through multi-component soil and water. This technique uses passive magnetic gradiometry to detect underground and underwater ferrous pipes, and is unaffected by the presence of water. Commercial magnetometer-based pipe locators do not measure enough component of the magnetic field and the magnetic gradient to be able to correctly find the depth of the buried pipe. During Phase I, the feasibility of detecting and locating one ferrous pipe in the presence of other ferrous pipes in the vicinity will be studied.A magnetic tensor gradiometer based pipe locator will first find applications in the natural gas, petroleum, and the utility industries. In addition, the gradiometer could be easily adapted to find underground structures, underwater vehicles, buried current-carrying conductors, buried unexploded ordnance and mines and concealed weapons.

这个小企业创新研究（SBIR）第一阶段项目将演示使用磁张量梯度测量来定位和确定埋在地下和/或淹没在水下的铁质管道深度的可行性。 地下管道的检测和定位对于公用事业、天然气和石油工业非常重要。 现有的技术，如探地雷达受到许多限制，包括无法准确地扫描多组分土壤和水。 这种技术使用被动磁梯度测量法来探测地下和水下的铁质管道，并且不受水的影响。 商用的基于磁力计的管道定位器不能测量足够的磁场分量和磁梯度以能够正确地找到埋置管道的深度。 在第一阶段，将研究在附近存在其他含铁管道的情况下检测和定位一个含铁管道的可行性。基于磁张量梯度计的管道定位器将首先在天然气、石油和公用事业行业中找到应用。 此外，梯度仪可以很容易地用于寻找地下结构、水下运载工具、埋在地下的载流导体、埋在地下的未爆弹药以及地雷和隐藏的武器。
