WDA相关法时间延迟估计

互联网摘选

The WDA ( acronym of Wavelet, Detail and Approximate) cross-correlation method based on wavelet transform was developed in consideration of measuring ultrasound echo signals to reduce the effects of noise, template window sizes and flaws on the time delay estimate using cross-correlation methods.

为了消除噪声、模板窗口大小和缺陷特征等因素对相关法时间延迟估计的影响，结合检测超声回波信号的特点，提出了基于小波变换的相关法时间延迟估计方法。
