摘要/Abstract

摘要： 电磁波传播理论与弹性波的传播理论有许多类似的地方，两者遵循同一形式的波动方程，因此可以把石油地震勘探的高频补偿技术引入到探地雷达的资料处理中。但该技术是在对近地表微测井直达波资料分析的基础上对叠后地震数据进行高频补偿的一种方法，而在实际的探地雷达探测中一般都不会同时去做一套微测井资料。基于这样的情况，通过对探地雷达反射子波的分析，总结一套直接利用探地雷达的原始记录就可以做频率补偿的方法，从而达到提高数据分辨率的目的。

Abstract: Since the electromagnetic wave propagation theory is similar to that of elastic waves, and both satisfy wave equation, the article plan to import the high-frequency compensation technology in oil seismic exploration to the GPR. However, the technology is a way which compensates the high frequency of the post-stack seismic data based on the analysis of the near surface micro-seismogram logs direct wave, and we don’t commonly make a set of micro-seismogram logs at the same time of the GPR survey. On this reason, through analyzing the GPR reflection wallet, we conclude a method which can make the frequency compensation using the originality record of GPR directly, and increase the GPR data resolution finally.

Key words: frequency compensation, absorbing compensation reverse filter, spectrum
