9403925 Zhdanov The PIs will develop algorithms for better imaging, delineation and characterization of underground structures by using electromagnetic geophysical data. The EM migration algorithm is a stable procedure that accurately restores the phase of the upgoing field inside the Earth. It is also computationally efficient compared to previous techniques. The PIs will expand the utility of their present 2D migration method and extend their method to 3D for borehole as well as surface EM data. ****

小行星9403925 研究所将利用电磁地球物理数据开发算法，以便更好地对地下结构进行成像、描绘和定性。 电磁偏移算法是一个稳定的过程，准确地恢复地球内部的上行场的相位。 与以前的技术相比，它也是计算效率高的。 PI将扩展其现有的2D偏移方法的效用，并将其方法扩展到3D钻孔以及地面EM数据。 ****
