摘要

电磁波在地下的传播速度是探地雷达合成孔径成像算法的关键参数。传统的地下电磁波传播速度估计采用介电常数测量法。然而，这种方法在实际应用中往往非常不方便，特别是当地下埋藏的物体很危险时。针对探地雷达探测浅埋小目标图像呈现双曲线几何形状的特点，本文提出了一种利用双曲线拟合估计电磁波地下传播速度并利用仿真数据进行验证的方法。实验结果表明，本文提出的算法是非常有效的。

Estimation on Underground Electromagnetic Wave Velocity Based on Characteristics of Shallow-Buried Small Target Echo

The underground transmission velocity of electromagnetic wave is the key parameter for synthetic aperture (SA) imaging algorithm of ground penetrating radar (GPR). The traditional estimation on underground electromagnetic wave transmission velocity adopts the method of measuring dielectric constant. However, this kind of method is often very inconvenient in practical application, especially when underground buried objects are dangerous. According to this nature that the image of ground penetrating radar (GPR) for shallow-buried small target presents the geometric shape of hyperbola, this paper puts forward a kind of method that uses hyperbolic fitting to estimate the underground transmission velocity of electromagnetic waves and utilizes simulation data for verification. The experimental results show that the algorithm proposed by this paper is very effective.
