摘要
根据探地雷达的探测原理及技术参数影响因素,提出了工作频率的选择方法。以广州和商丘两地的两个探测实例,介绍了如何根据管径、埋深确定天线频率、天线距、采样点距、时窗等探地雷达技术参数;并选择已知埋深的管线,对波速进行实地测定,以便在探地雷达剖面上对目标体的埋深作出精确解释。
According to detecting principle and technical parameter influential factors of ground penetrating radar, take two detecting examples from Guangzhou and Shangqiu, introduce how to determine ground penetrating radar parameters of antenna frequency and spacing, sampling spacing, time window judge by pipeline diameter and buried depth. Based on assigned pipeline buried depth, determine wave velocity on the spot in order to work out exact solution of target buried depth on the ground penetrating radar section.
