摘要

探地雷达(GPR)的天线设计需要考虑许多与地下传感相关的特征。通常，这样的天线被放置在离被调查物体表面很近的地方。它们应该是宽带的，以确保良好的分辨率，能够在低频率上工作，以提供合理的穿透深度，并且足够敏感和便携。本文介绍了两种最流行的天线——单向螺旋天线和维瓦尔第型锥形槽天线(TSA)的对比分析结果。

Frequency domain reflectometry of buried objects using wideband antennas

Antenna design for ground penetrating radar (GPR) requires to take into account a number of features related to subsurface sensing. Usually, such antennas are placed very closely to the object surface under investigation. They should be wideband to ensure good resolution, capable to operate on low frequencies to provide reasonable penetration depth, and be sufficiently sensitive and portable. Here we present the results of comparative analysis performed for two types of most popular antennas - the unidirectional spiral antenna and the tapered-slot antenna (TSA) of Vivaldi type, designed and fabricated by the authors.
