Application of the Wavelet Transform to Isostatic Analyses in Australia

小波变换在澳大利亚均衡分析中的应用现有的确定地球均衡响应的方法假设理想但不现实的条件。本计画将发展一种利用二维小波变换进行均衡分析的新技术。该工具可以在空间域中解析地球物理数据的谱分量，从而避免了传统傅立叶分析中出现的问题。通过创新的处理方法，可以根据重力和地形数据绘制地壳厚度图，这是一项通常留给昂贵的地震实验的任务。子波功率谱的分析还将通过识别以前未知的沉积盆地而使勘探工业受益。

Application of the Wavelet Transform to Isostatic Analyses in Australia. Existing methods of determining the Earth's isostatic response assume ideal but unrealistic conditions. This project will develop a new technique for isostatic analysis, using the two-dimensional wavelet transform. This tool can resolve spectral components of geophysical data in the space domain, thus avoiding the problems arising during the conventional Fourier analysis. With innovative processing methods, maps of the crustal thickness from gravity and topography data can be generated, a task usually reserved for costly seismic experiments. Analysis of the wavelet power spectrum would also benefit the exploration industry by identifying previously unknown sedimentary basins.
