中文摘要：

将现场实验得到的相思树根系的探测信号图与利用Gpr Max V2.0软件模拟的根系信号图对比分析,得出根的埋深、水平间距、根的直径是根目标反射信号产生差异的主要影响因素。为得到更接近实际根系生长状况的图像数据,利用Gpr Max V2.0模拟了交错根系的图谱,并对其反射信号进行了分析;探查出交错根系不同角度的模拟图像的差异及其产生原因,进一步证实了利用Gpr Max V2.0软件模拟探地雷达探测树木根系的有效性。

英文摘要：

We used GprMaxV2.0 software to comparatively analyze the acacia rachii roots detection signal of field experiments and the simulation images. The buried depth,horizontal spacing,and the diameter of the roots are the main influencing factors on the reflection signal differences of the roots target. In order to acquire the image data approach to the actual growth situation,we simulated the crisscross root images using GPRMaxV 2.0,and analyzed the roots reflected signal. We found out the differences and the reasons of the simulated images from the different angles of the crisscross roots,and confirmed the effectiveness of GPRMaxV 2.0 to simulate the tree roots detection by GPR.
