摘　　要：EH-4系统电磁测深自带数据处理软件IMAGEM基于DOS界面,使用不方便,数据再处理困难,效率低.作者致力于开发一套新EH-4系统电磁测深数据处理软件,该软件能够实现EH-4系统电磁测深数据的便捷、高效处理,并且方便在数据处理过程中引进最新的去噪,反演等技术,还方便在新发展起来的多种操作系统上运行.本文主要研究EH-4系统电磁测深数据处理的全过程:包括原始时间序列频谱分析、功率谱计算、视电阻率及阻抗张量计算、拟二维反演等.在此基础上,基于Microsoft.NET Framework开发出了一套全新,完全脱离IMAGEM、能够在Windows XP、VISTA及Windows 7等多系统下运行的EH-4系统电磁测深数据处理软件EH4DataProcessingSystem.该软件界面友好,使用灵活方便,便于进一步引进先进的去噪、反演等数据处理技术.实例应用表明,其数据处理效果较好.EH-4 system is widely used for high frequency magnetotellruic （HMT） soundings. Its own data processing software IMAGEM, based on the DOS system, is not convenient to operate, also the efficiency of data reprocessing is low. And the new methods of noise elimination and inversion can he hardly brought in for data processing. So this article aims to make a more convenient and more efficiency data processing software for EH-4 system. Firstly, it studies the whole process of the data processing, including computing the power spectral from the raw time series, and computing the apparent resistivity together with the tensor impedance, and pseudo 2D inversion. Based on the computing, new data processing software named EH4DataProcessingSystem is developed in Microsoft. NET Framework. It is running well in Windows XP, VISTA, and Windows 7 systems. Application proves this software feasible and valuable.
