摘要

大面积土壤含水量制图是农业、生态、土木工程以及洪水和水资源管理等各个领域必不可少的过程。大多数可用的测量土壤水分含量的方法既繁琐又昂贵。土壤含水量会影响土壤的电性。在探地雷达系统中,土壤电学性质会影响接收到的反射波。关于探地雷达(GPR)反射波传播的详细信息可能对提取土壤含水量有用。提出了基于最小二乘法的探地雷达系统土壤含水量信息提取模型。对该方法进行了理论和数值研究,结果表明该方法能够有效地从探地雷达资料中提取表层土壤的体积含水量和厚度信息。

Extraction model of Soil Water Content Information based on Least Square Method for GPR
Mapping the soil water content in large area is an essential process in various fields such as, agriculture, ecology, civil engineering, as well as flood and water resource management. Most of the available methods to gauge soil moisture content are tedious and expensive. Water content of the soil will affect the soil electric properties. In GPR system, the soil electrical properties will affect the received reflected wave. Detailed information about Ground Penetrating Radar (GPR) reflected wave propagation is potentially useful for extracting the soil water content. Extraction model of Soil Water Content Information based on Least Square Method for GPR System is proposed in this paper. Theoretical and numerical studies on the proposed method have been performed and the results show that the proposed method is useful to extract information about volumetric water content and thickness of topsoil from the GPR data.
