Progress on detection of contamination content in the contaminated soilbased on Ground Penetrating Radar
基于探地雷达回波信号获取污染土壤中污染物含量的研究进展

From three aspects,application of Ground Penetrating Radar(GPR) to surveying the contaminated soil,dielectric model evolution of the contaminated soil and the ways to obtain the soil dielectric constant,this paper makes a review about the research of domestic and foreign scholars who made use of ground penetrating radar technology to detect the soil pollution.We indicate that taking the soil dielectric constant as the link,it is possible to obtain the dielectric constant from the GPR echo signal by adopting appropriate methods,through the nerve network technology to domesticate and establish the relationship between the dielectric constant and various kinds of parameters in the contaminated soil,so that to actualize the quantitative measurements of many kinds of pollutant contents in the contaminated soil.
