摘要
由于商业探地雷达天线价格昂贵,又比较笨重,很多测量参数不能任意修改或修改起来比较困难,且在室内做实验又很不方便,所以,设计一种造价低,小巧方便且效果较好的天线显得很有意义.基于这样的考虑,本文从实用的角度出发,采用半定量化的方式较详细的介绍一种简易探地雷达天线的制作方法,并辅以网络分析仪对其实际应用效果进行分析研究.实验证明,对于常规的探地雷达实验研究,该天线在性能上已达了要求,是有效的,可行的.
The commerce Ground Penetrating Radar （GPR） antenna is expensive, heavy and many parameters can＇t not be modified freely or be modified difficultly, using it to make experiment indoors is not so convenient. Thus, it＇ s significant to design an antenna which is cheap, small, convenience and better effect. Base these considerations, in this article, we＇ll detailedly introduce one way to make a facility GPR antenna in half fix quantity method, and have an analysis of its practice application effect with the Network Analyzers. The experiments prove that the antenna can be up to the requirement in the performance for usual GPR experiment research, and it is effective and feasible.
