摘　　要：该文根据地质雷达信号的特点,采用最小熵反褶积法对雷达信号进行处理。该方法可以有效地去除子波的拖尾现象,改善地质雷达剖面记录,提高信号的垂向分辨率和信噪比。采用该方法对某工程基岩面和岩溶地质雷达探测数据进行处理,结果表明该方法是一种比较有效的雷达资料处理方法。According to the characteristics of ground penetrating radar （GPR） signal, the minimum entropy deconvolution method is applied for the signal processing of GPR. The method can effectively removes the delayed tail of GPR wave, and it can improve the GPR profile records and improves the vertical resolution and signal to noise ratio of the signal. Using the minimum entropy deconvolution to process the GPR detection of the rock surface and the detecting data by GPR of an engineering, the results show that this method is a very effective method for processing the GPR data.
