本文给出了最近十二年间１００个电磁波层析成像实例的统计资料，分析了电磁波层析的勘查精度与像元尺寸的关系，以及电波仪的频率设置，野外测量时的覆盖次数、方程组的欠定性等问题，并得出结论：为了提高电磁彼层析的实用水平，需要研制频带宽、功率大和天线短的新一代电波仪；也需要研究欠定方程组模式下的成像方法和重建算法。与此同时，叙述了重建算法研究中模型设计与实际情况脱节的不足之处。
In this paper, the statistical data of 100 examples of electromagnetic tomography in the recent 12 years are given. The relationship between the exploration accuracy of electromagnetic wave tomography and the pixel size is analyzed, and the frequency settings of the radiometer, the coverage times in the field survey, And concluded that in order to improve the practical level of the electromagnetic layer, it is necessary to develop a new generation of radiowavers with wide frequency band, large power and short antenna. It is also necessary to study the imaging methods and reconstruction under the undetermined equation mode algorithm. At the same time, it describes the shortcomings of the model design and the actual situation in the research of reconstruction algorithm.
