摘要
探地雷达因其便捷、高效、无损的优势目前被广泛应用于道路地下病害体探测任务中,但雷达图像识别又缺少统一的解释标准,所以亟需为病害体探测提供判别依据。因GPRSIM探地雷达正演软件可自定义模型形状、天线频率大小及正演速度快等优点,所以研究基于GPRSIM设计了不同填充类型、形状、规模、埋深、天线中心频率的道路路基空洞病害模型进行正演模拟研究,并分析总结病害雷达特征。其结果对雷达图像的解译具有重要的指导作用,同时,也为病害体识别提供了客观的理论依据。
Ground penetrating radar is widely used in road underground disease detection tasks because of its advantages of convenience,high efficiency and non-destructiveness.However,there is no uniform identification standard for radar images to be recognition,so it is urgent to provide a basis for disease detection.GPRSIM ground penetrating radar forward modeling software can customize the shape of the model,the antenna frequency and the fast speed of forwarding.Therefore,a disease model of road subgrade void with different filling types,shapes,scales,depths and antenna center frequencies based on GPRSIM was designed.The void disease model carried out forward simulation research,and the characteristics of radar images were summarized and analyzed.The results have an important guiding role in the interpretation of radar images.At the same time,it is also provides an objective theoretical basis for disease identification.
