摘　　要：随着工程技术的高速发展,地质雷达近几年被广泛使用。开展地质雷达的校准工作,可有效保证其量值的准确可靠。目前针对地质雷达的国家计量技术规范尚未制定,仅制定相关的行业计量技术规范,其测量方法不尽相同,各有特点。在此基础上针对空气中雷达波速测量校准方法进行探讨。实验结果表明,优先采用垂直方向测量间距,且测量间距的选取应不小于2倍雷达电磁波波长。With the rapid development of engineering technology,ground penetration radar has been widely used in recent years.The calibration of ground penetration radar can effectively ensure the accuracy and reliability of quantity.At present,the national metrological technical specifications for ground penetration radar have not been formulated,and only the relevant industrial metrological technical specifications have been formulated.The measurement methods are different and each has its own characteristics.On this basis,the method of measuring radar wave speed in the air is discussed.The experimental results show that the vertical measurement distance is preferred,and the measurement distance should not be less than twice the radar electromagnetic wave wavelength.
