论文部分内容阅读
地下雷达 (subsurface radar),又叫做探地雷达 (ground probing radar),是雷达技术的一个新的、日益发展的应用领域。英国等一些国家对此作了大量研究,在英国期刊IEE Proceedings,pt.F 1988年8月号上,集中刊载了有关文章。本文 (Introduction toSubsurface Radar) 是其中的一篇综述文章,文中对探地雷达的发展史、设计原則和发展前景作了概述,并对有关问题,如地物的介电特性、信号调制方式,天线结构和信号处理等,作了较为详细的介绍。为了向读者概略介绍地下雷达的概况,本刊拟分两次刊登这篇译文。原文较长,为了节省篇幅,我们只登了其中第一、二、七和八节的译文。
The subsurface radar, also known as the ground probing radar, is a new and growing field of application of radar technology. A number of countries, such as the United Kingdom, made a great deal of research on this topic and published articles focused on the August 1988 issue of the British journal IEE Proceedings, pt.F. This article (Introduction to Suburface Radar) is one of the review articles, which summarizes the development history, design principles and development prospects of GPR, and analyzes the related issues such as the dielectric properties of the ground objects, the signal modulation method, the antenna Structure and signal processing, made a more detailed introduction. In order to give the reader a rough overview of the underground radar, this article is to be published in two translations. The original text is longer. To save space, we have posted only the first, second, seventh and eighth translations.
