模糊模式识别在电磁测深资料解释中的应用
|
摘要
研究了在横、纵向同时求模糊关系的高层次模糊模式识别方法，并且把这一方法应用于EH－4电磁测探资料的解释。对于大地电磁测深方法，干扰比地震或其它可控源电磁法要强，利用单一参数解释就会不够准确。EH－4大地电磁测深仪，在记录电磁场的5个分量后，可以现场处理出14个反映地电参数的信息。利用我们研制的模糊模式识别方法，对这14个信息因子进行地电参数的解释，收到了较好的效果。
A high-level fuzzy pattern recognition method, which can simultaneously derive fuzzy relations in transverse and longitudinal directions, is studied in this paper, and then the method is appliedto electromagntic sounding data interpretation. Disturbances in MT methed are stronger than seismicand other controlled-source EM methods; MT data interpretation by single parameter is not very precise.The EH-4 MT sounder can obtain 14 kinds of geoelectric parameter information from recorded five EMfield components through in-site processing. We use the fuzzy pattern recogmtion method presented inthe paper to perform geoelectric parameter interpretation on these 14 information factors and a good effect is achieved.
