近地表应用的范围不断扩大[1]，特别是对于地面应用，部署了越来越高的空间采样密度[2]。在广泛的地球物理方法中，小回路频域电磁（FDEM）仪器通常用于同时记录多个EM属性的变化[3]-[7]。这样的仪器通常结合至少一个发射器与一个或多个接收器。所得到的发射器-接收器对通常被配置为水平共面（HCP）、垂直共面（VCP）、垂直同轴（VCA）或垂直（PRP）取向[8]、[9]。可以在对称（例如，HCP、VCP和VCA）和不对称（例如，PRP）线圈配置[10]，[11]与测量航向相关。虽然前者呈现不受采集方向影响的各向同性响应，但非对称配置将基于测量航向产生不同的响应。
The range of near-surface applications whereby the electrical and magnetic properties of the subsurface are investigated expands continually [1], and, particularly for terrestrial applications, increasingly higher spatial sampling densities are deployed [2]. Within the broad range of geophysical methods, small-loop frequency-domain electromagnetic (FDEM) instrumentation is often used to record variations of multiple EM properties simultaneously [3]-[7]. Such instruments typically incorporate at least one transmitter in combination with one or more receivers. The resulting transmitter-receiver pairs are commonly configured in either a horizontal coplanar (HCP), vertical coplanar (VCP), vertical coaxial (VCA), or perpendicular (PRP) orientation [8], [9]. A distinction can be made between symmetrical (e.g., HCP, VCP, and VCA) and asymmetrical (e.g., PRP) coil configurations [10], [11] in relation to survey heading. Although the former render an isotropic response unaffected by the acquisition direction, an asymmetrical configuration will produce different responses based on survey heading.
