Time-domain multi-channel deconvolution is put forward to estimate receiver function, to improve resolution. Based on the deconvolution results for those individual teleseismic P waveforms, a number of events with good quality are selected to form multi-channel signals, the vertical components are regarded as inputs, and radial and transverse components are taken as outputs. Least-square error is used to design the multi-channel filter, to get the common filter factors, i.e., receiver function. Both synthetic and real data experiments show that multi-channel deconvolution is an effective approach to measure receiver function, especially, it can recover the weak converted phases from the upper mantle. |
