重力场数据处理中小波母函数的选择
THE SELECTION OF WAVELET GENERATING FUNCTIONS IN DATA-PROCESSING OF GRAVITY FIELD
【摘要】 在分析小波分析技术的本质和小波母函数性质的基础上 ,考虑待分析信号的特性 ,从而给出一种小波母函数的选取方法。利用上述方法选取的小波母函数进行小波分析将获得较优的效果
【Abstract】 Based on an analysis of the nature of wavelet analytical technique and the property of wavelet generating function, the authors took into account the chatracteristics of signals to be analysed and then posed a method for selecting wavelet generating function. Experiments show that the application of wavelet generating functions selected with this method to wavelet analysis can yield relatively satisfactory result.
