硕士论文-探地雷达的分析和研究，正文共70页。
【摘要】 探地雷达技术是本世纪70年代以来迅速发展起来的一门新技术，由于国外研究起步早，所以技术比较先进，但国内各科研单位在充分借鉴国外技术的基础上，近年来在探地雷达的研究上也取得了很大的进步，一批国产探地雷达样机也相继问世。 本文系统地分析了探地雷达软硬件技术，分析过程中以探地雷达接收和发射电路为重点，论文主要可分为以下几部分： 一、引言，介绍了探地雷达技术的历史、现状及发展趋势。 二、探地雷达原理分析，由电磁场及雷达方程的一般形式推导出适用于探 地雷达的基本原理。 三、接收系统和发射系统分析，分析中重点涉及了取样和雪崩。 四、杂波消除分析，这是软件上对信号的处理。 五、天线分析，重点是行波天线的加载技术。
【Abstract】 Ground-Penetrating Radar (GPR) is a new technique which develops rapidly from the 1 970s. The overseas technique of GPR is more advanced than that of domestic because they began the research in this field earlier than us. On the base of overseas advanced technique for reference, we have made great progress in the research of GPR. For example, Some sample GPR made in our country has been used in many fields. In this paper, the author analyses the hardware and software of GPR systematically. The emphasis of this paper is on the receiving system and sending system of the circuit. The paper can be divided into four main parts: 1~ Introduction. In this part, the history, present situation and future development of GPR are described. 2 ~. GPR principle analysis. In this part, the author deduced the principle used for GPR by the general principle of electromagnetic and radar equation. 3~ Analysis on the receiving system and sending system. Sampling and snowslide are described in detail in this part. 4~. Analysis on the elimination of interference signal. This is the disposal of the software. 5 ~. Analysis on antenna. The emphasis of this part is the loading technique of travelling wave antenna.
