The Convolution Integral Arithmetic of Harmonic Wavelet Filter in the Data Processing of Aerial Gravity Measurement
Pages: 4-6
Year: Issue:  2
Journal: Hydrographic Surveying and Charting

Abstract: 数据的滤波提取是航空重力测量数据处理的一个重要环节.谐波小波滤波器在频域具有良好的盒形谱特征,可以较好地实现信号的滤波.但谐波小波滤波器是一个连续函数,航空重力测量采集的信号是离散的,无法直接进行卷积运算.讨论了谐波小波用于航空重力数据滤波处理时的卷积运算处理方法,给出了谐波小波频域卷积的算法实现过程和仿真算例.
