中文摘要: |
深部勘探电法仪器通常由于信号微弱,并且存在较强的人文干扰、电磁耦合干扰等多种干扰因素,以至于运用传统的或者单一的方法很难得到较高质量的数据。该研究以现代数字信号处理方法为主,并辅以合理的模拟信号调理相结合的方法来达到提高深部勘探电法仪器数据采集质量的目的。文章通过介绍基于2n伪随机信号的深部勘探电法仪器的数据采集、处理过程,以及其在工程实践中的应用实例,阐述了提高深部勘探电法仪器数据采集质量的方法体系及应用效果。 |
英文摘要: |
It is difficult to get higher quality data using traditional or single methods due to weak signals, strong human interference, electromagnetic interference and other interference factors are demons in deep exploration for electrical instruments. This research is based on the modern digital signal processing methods and the combination of reasonable analog signal conditioning to improve the quality of data in deep exploration for electric instruments. This paper introduces the acquisition and processing of data in deep exploration based on 2n pseudo-random signal and its application in engineering practice, and elaborates the method and application effect of improving the quality of data in deep exploration. |
