Abstract
Summary form only given, as follows. There are several types of time-varying filters designed for processing of nonstationary data. The old method of dividing the nonstationary sequence into piecewise stationary sections has been modified to design an adaptive filter for multichannel time-varying seismic data. The design principle is illustrated through some synthetic seismic traces. It is found that the adaptive multichannel filter suppresses the coherent noise present in the seismogram
