介绍铁路路基探地雷达探测模型正演研究。开发研制出适宜不同衰减类型、不同中心频率天线的雷达记录合成软件系统。结合实测数据,模拟合成了路基地层雷达记录曲线,而且系统地研究了路基空区中充填不同介质和非均匀介质的差异对雷达成像特征造成的影响,取得良好效果。
A Study on Forward Modeling of Ground Penetrating Radar Detection Model for Railway Subgrade. Developed a radar recording and synthesis software system suitable for different attenuation types and different center frequency antennas. Combined with the measured data, the ground-based radar recording curve was simulated and the effect of the difference of different media and inhomogeneous media filled in the subgrade on the radar imaging characteristics was systematically studied.
