Ground radar frequency compensation and correction technique

Ground radar wave propagation in ground is influenced by the attenuation,dispersion and other interference,to certain extent,which will limit ground radar detection resolution and final interpretation effect.In order to reduce the attenuation,dispersion and the impact of interference,this paper presented a frequency compensation and correction method,which was based on the stratum system response model,through computing a frequency compensation and correction factor from the ground penetrating radar raw data,the raw recorder spectrum will be corrected,which will improve the ground penetrating radar profile record and enhance the vertical detection resolution.For better understanding of the effect of the stratum spectrum correction method,this article gave detailed introduction of its principle and application effect,but also compared its effect with that of sharp pulse deconvolution,which can further prove that the stratum spectrum correction method has advantage in reducing noise and enhancing resolution of the ground penetrating radar data.
