摘    要：探地雷达信号十分复杂,包含各种干扰,使得实时记录图像多变且不易分辨,利用小波变换空间域一频率域双重局部性的特点,对雷达信号进行奇性检测,不仅能确定信号奇性的空间位置,还能压制噪声.

Abstract: The signal of ground probing radar (GPR) is very complex, including noises, which makes the radar record difficult to recognize and interpret. In this paper, based on the property of the double localization in space-frequency domain of the wavelet transfrom, as well asits focusing function, the singularity of the GPR signal is detectpd by a new way. The numerical simulation of radar wave through a multilayered medium shows that the new method is very effective' The result is significant to the tomography of the radar data.
