| 摘 要： | 概括了探地雷达野外工作的基本方法,介绍了探地雷达现场工作测线（网）布置的基本原则,并总结了探地雷达野外测量时工作参数的选择原则.这些工作参数包括工作天线主频、采样时间窗的大小、空间采样步长（记录道距）、时间采样间隔、天线距大小.比较了“离散”测量与“连续”测量之间的关系,并讨论了在采用“连续”测量方式时天线的移动速度、仪器采样速率与所要求的空间采样率之间的关系.

| Abstract: | The basic principle for the layout of GPR survey line(or grid) was summarized on the three basic operation modes,i.e.,reflection mode,common mid point mode and transillumination mode,and the basic principles for the choice of GPR field operation parameters were introduced,which included the center frequency of antenna,the maximum time window,the spatial and temporal sampling intervals,and the separation 'between' the transmitting and receiving antennas.The relationship between 'discrete' and 'continuous' GPR measurement was described,and the relationship among the antenna moving velocity,the sampling rate of GPR system and the required spatial sampling interval were discussed in detail. |
