Multi - channel deconvolution, based on multi - channel signal analysis, is presented to recover receiver function from three - component teleseismic p waveforms clustered within certain backazimuth and epicenter distance, to increase the resolution of receiver function. wavelet inversion is also introduced to broadband receiver function, to solve for nonuniqueness cased by linear approximation of nonlinear problem, and broadband receiver function is decomposed into multi - resolution versions, and the inversion result for the low - resolution version is iteratively taken as the initial model for the high - resolution, and gradually obtain the inversion model for broadband receiver function
為克服廣義線性反演對初始模型的依賴性，並保持其快速收斂的特點，本文首次將小波變換引入到接收函數波形反演，將接收函數分解到不同的分辨尺度上，分別進行廣義線性反演，並將低解析度的反演結果作為高解析度反演的初始模型，漸近地獲取寬頻帶接收函數的模型，克服了非線性問題線性化帶來的非唯一性。 -
