摘要： 使用多频阵列探地雷达对发射场坪缺陷进行检测，可获得地下不同深度和分辨率的目标信息。然而，多频阵列探地雷达生成的数据量巨大，不同频率的雷达数据无法合并处理给成像和异常解释都造成障碍。针对此问题提出了一种多频阵列探地雷达测量数据实时成像方法，从深度和通道两个方向进行射线投射，更全面地展示不同深度的地下异常体的信息。实测数据处理结果表明，本方法能有效保留地下异常目标的基本信息，实现快速、高精度显示，满足发射场坪快速检测的应用需求。

Abstract: Using multi-frequency array Ground Penetrating Radar (GPR) to detect defects in launch site pavements can obtain target information at different depths and resolutions. However, the vast amount of data generated by multi-frequency array GPR and the inability to merge data from different frequencies pose challenges for imaging and anomaly interpretation. To address this issue, a real-time imaging method for multi-frequency array GPR data is proposed, which utilizes ray projection in both depth and channel directions to more comprehensively display information on underground anomalies at different depths. The processing results of measured data indicate that this method effectively retains the basic information of underground anomalies, achieving rapid and high-precision display, thus meeting the application requirements for the rapid detection of defects in launch site pavements.

Key words: Ground Penetrating Radar (GPR), Launching site detection, Ray casting
