摘要/Abstract

摘要： 轻非水相流体（LNAPL）泄漏后会对土壤和地下水造成严重污染，为了准确探测出LNAPL泄漏范围，本文将GPR天线-目标极化的瞬时属性分析方法应用于轻非水相流体污染土壤探测的研究中。采用注入柴油的石英砂砂箱在实验室建立污染土壤模型，利用探地雷达对该污染土壤分别进行天线方位为0°、90°的测量。LNAPL土壤污染物形状、大小、结构并不规则，因此可以通过0°和90°方位天线测量来分析天线-目标极化特征，了解目标物的走向、形状等地下介质信息。通过对预处理后的包含天线-目标极化特征的信息进行瞬时属性分析，LNAPL污染范围可以被清晰地识别，提高了GPR探测能力。

Abstract: In this paper, we apply the instantaneous attribute analysis method to ground penetrating radar (GPR) antenna-target polarization to detect the Light Non-Aqueous Phase Liquids (LNAPL) contaminated soil. We set up a model of LNAPL contaminated soils using quartz and diesel in laboratory and use the GPR to detect the contaminated soils with 0° antenna and 90° antenna, separately. The shape, size, and structure of LNAPL soil are not regular. Therefore, we can analyze the antenna-target polarization characteristics through 0° antenna measurement and 90° antenna measurement, and get the underground material information such as the direction and shape of the target. Through analyzing the instantaneous attribute of the pre-processed information including antenna-target polarization characteristics, the LNAPL contamination range can be clearly identified, and the detection ability of GPR can be improved.

Key words: ground penetrating radar, soil contaminants, light non-aqueous phase liquid, antenna-target polarization, instantaneous attribute analysis
