弱信号增强处理是探地雷达数据处理中的一个重要环节，而且是探地雷达数据处理难以解决的问题。弱信号在两 方面使其不易于直接从探测剖面上识别出来：一是本身信号强度小且受到随机噪声的干扰；二是存在浅部强信号的明显反 差，视图上难以识别。本文根据小波变换的特征提出一种信号增强方法，即多尺度小波变换信号增强法。-Ground-penetrating radar based on wavelet transform weak signal enhancement

The word Radar is the acronym of Radio detection and ranging. Radar is an active instrument, which measures the echo of scattering objects, surfaces and volumes illuminated by an electromagnetic wave internally generated belonging to the microwave po
