摘　　要：在使用探地雷达对道路进行探测时,薄层介质的存在使探测受到探地雷达垂直分辨率的限制,导致反射信号重叠;提取起伏介质双程走时的过程中容易偏离真实值,进而影响探测结果。为了解决这些问题,本文提出了一种基于改进猎人猎物算法的层状介质反演算法。该算法首先利用正交匹配追踪算法提取各层的双程走时并确定层状介质的参数取值范围,然后对较深层界面反射信号进行振幅补偿,最后通过改进猎人猎物优化算法精确反演。仿真结果表明,该算法在薄层介质和起伏介质存在时能提高参数反演的准确性。When using ground penetrating radar(GPR)to detect roads,the presence of thin-layered media limits the detection due to vertical resolution of GPR,resulting in overlapping reflection signals.And in the process of extracting the two-way travel time of undulating media,it easily deviates from the true value,which affects the detection results.To address these issues,an inversion method for layered media based on improved hunter-prey optimization algorithm is proposed.The orthogonal matching pursuit algorithm is adopted to extract the two-way travel time of each layer and determine the parameter range of the layered media.Then,the amplitude of the reflected signal at the deeper interface is compensated.Finally,the improved hunter-prey optimization algorithm is applied for precise inversion.Simulation results show that the proposed method can improve the accuracy of parameter inversion in the presence of thin-layered media and undulating media.
