This paper introduced the basic theories of wavelet .

本文介绍了微波的基本原理。

Theoretic calculation show that wavelet can be reconstruct from double spectrum of theoretical seismic data for seismic wavelet with different characters.

理论计算表明，对不同性质的地震子波，均可从理论地震记录的双谱中重构子波。

It is then subject to such mathematical indignities as wavelet decomposition, multi-resolution Fourier analysis, polyphase filtering and discrete cosine transformation.

接下来它还要经过一些数学处理程序，比如小波分解，多重分辨率傅立叶分析，多相过滤，离散余弦变换等。
