    • The disclosure provides an electromagnetic (EM) sensor system and method that permits rapid and non-invasive measurement of material properties using measurements of the dispersion of EM energy signals over a wide band of frequencies, including second and higher order moments. The EM energy can be a pulse signal, including an ultra-wide band ("UWB") pulse signal. A plurality of signals can be incrementally projected through the material in a grid. The grid can generally include a series of projections through the material of an object at different angles. The further analysis of the dispersion characteristics of the EM energy signal provides a measure of added features that assist in improved characterization of the material properties. In at least one embodiment, the results of processed pulses through the object can be used to form a two-dimensional or three-dimensional image of the material for the particular property being measured.
    • 本公开提供了一种电磁(EM)传感器系统和方法,其允许使用在包括二阶和更高阶矩的宽频带上的EM能量信号的离散度的测量来快速且非侵入地测量材料性质。 EM能量可以是脉冲信号,包括超宽带(“UWB”)脉冲信号。 多个信号可以通过网格中的材料递增投影。 网格通常可以包括以不同角度穿过物体的材料的一系列投影。 对EM能量信号的色散特性的进一步分析提供了一些有助于改进材料性能表征的附加特征的量度。 在至少一个实施例中,通过物体的经过处理的脉冲的结果可用于形成用于被测量的特定性质的材料的二维或三维图像。
