摘要

波速的测量在探地雷达的研究中一直是一个至关重要的课题

尤其是对地下目标进行定位和成像时;本文针对浅地层探地雷达接收信号的特征

抛弃传统的过零点检测和其他的边缘轮廓检测方法

提出用极值进行边缘轮廓检测的方法

从而对目标的提取更准确并且有较少的数据

减少了霍夫变换的计算量;通过对霍夫变换算法的分析

针对传统霍夫变换的缺点

提出了一种加FIR低通滤波器的改进霍夫变换;同时应用算法对实测数据进行了计算

证明所提算法比传统的霍夫变换方法有更高的测速准确度.

Abstract

The measurement of wave speed is always one of the key problems in the research of subsurface penetraing radar

particularly when the location and image of the targets in the ground are measured.On the basis of the signal features of subsurface penetrating radar

extraction of edge contours which uses zero-crossing points and others traditional methods are discarded.The method of extremum is given for extraction of edge contours.The edge contours of the targets can be extracted more accurately using the method of extremum and the new method generates less data for Hough transform.And according to the analysis of Hough transform and the deficiency of traditional Hough transform

an improved Hough transform is proposed in which a FIR low-pass filter is added to improve the accuracy of Hough transform.The improved Hough transform has better performance than the traditional Hough transform by the evaluation for the practical data.
