超声波具有波长短、有方向性、能量集中且强度大、振动剧烈的特点。

The main conclusions are: Mexican hat wavelet is anisotropic one, and it could detect pointlike singularities very efficiently. Morlet and Cauchy wavelet could be used to detect specific directions, and Cauchy wavelet has better direction selectivity than Morlet one. And it has been used to separate the wave field of Ricker. Its results are basically accurate and computation is more efficient.

主要结论有：Mexcian帽小波是各向同性的，主要用来检测点状信号分量，Morlet小波和Cauchy小波主要用来检测方向信号分量，并且Cauchy小波比Morlet小波的方向性要好，检测结果的分辨率要高；利用二维连续小波反变换，以合成的Ricker子波为模拟信号为例进行波场分离，提高了运算效率，实验结果基本上比较准确，还需要实际地震信号的进一步验证。
