我们报告了一种新型便携式磁标量三角测量和测距(STAR)技术的第一个原型的现场测试结果。在战略环境研究和发展计划(SERDP)的支持下，正在开发新的磁性传感器系统技术，以提供一个易于部署的磁性传感器系统，用于实时、逐点检测、定位和分类未爆弹药(UXO)和埋藏地雷等磁性目标。STAR技术基于多张量梯度计方法，该方法使用磁梯度张量大小，即“梯度-收缩类型”参数来执行磁性目标的DLC。磁力星敏感器使用标量函数对磁性UXO型目标的位置向量进行三角剖分，并计算目标的磁性特征向量。物体磁性特征的矢量分量为其类型的实时分类提供了基础，即是否类似于UXO。为了验证STAR概念的原理，并展示其在高迁移率磁传感应用中的优势，我们设计、建造了一台便携式星体梯度仪样机，并进行了现场测试。便携式梯度仪的硬件和软件是完全独立的，为磁性目标的实时DLC提供了实用和用户友好的能力。目标DLC参数：例如，距离、方位、仰角和磁性特征与全球定位系统时间和位置数据相关，并在夹在操作员安全眼镜上的平视显示器上近乎实时地显示(总延迟和3秒)。交互软件控制数据采集，执行信号处理以消除残余运动噪声影响，并运行STAR算法来生成和显示目标的DLC参数。现场测试已经证明了STAR概念的原理证明，并最终证明了该技术通过高度移动的传感平台对DLC具有独特的优势。虽然由个人携带和操作，但便携式传感器即使在每秒40度以上的旋转运动中也表现出非常坚固的、抗运动噪音的性能。现场测试结果有力地表明，便携式STAR技术可以为各种高度机动的传感平台(包括自主水下航行器)提供独特有效的、抗运动噪声的磁传感模式，用于UXO和水下水雷等磁性目标的DLC。
We report results of field tests of the first prototype of a novel man-portable Magnetic Scalar Triangulation and Ranging (STAR) technology. The new magnetic sensor system technology is being developed with support from the Strategic Environmental Research and Development Program (SERDP) to provide an easily deployable magnetic sensor system for real-time, point-by-point Detection, Localization and Classification (DLC) of magnetic targets such as Unexploded Ordnance (UXO) and buried mines. The STAR technology is based on a multi tensor gradiometer approach that uses magnetic gradient tensor magnitudes, i.e., "gradient- contraction-type" parameters to perform DLC of magnetic targets. The magnetic STAR sensor uses the scalar functions to triangulate a magnetic UXO-type target's position vector and to calculate the target's magnetic signature vector. The vector components of an object's magnetic signature provide a basis for real time classification of its type, i.e. UXO-like or not. In order to provide proof of principle of the STAR concept and demonstrate its advantages for high mobility magnetic sensing applications, we designed, constructed and field-tested a prototype man-portable STAR Gradiometer. The portable gradiometer's hardware and software are completely self- contained and provide a practical and user friendly capability for real time DLC of magnetic targets. Target DLC parameters: e.g., range, bearing, elevation and magnetic signature are correlated with Global Positioning System time and position data and displayed in near real time (total delay < 3 seconds) on a heads-up display that clips onto the operator's safety glasses. Interactive software controls data acquisition, performs signal processing to remove residual motion noise effects and runs the STAR Algorithm to generate and display the target's DLC parameters. Field tests have demonstrated proof-of-principle of the STAR concept and conclusively demonstrated that the technology has unique advantages for DLC by highly mobile sensing platforms. While being carried and operated by a single individual, the portable sensor has demonstrated very robust, motion noise resistant performance even while undergoing rotational motion of more than 40 degrees per second. The field test results very strongly indicate that the man-portable STAR technology can provide a wide variety of highly maneuverable sensing platforms (including Autonomous Underwater Vehicles) with uniquely effective, motion-noise-resistant magnetic sensing modalities for DLC of magnetic targets such as UXO and underwater mines.
