This paper discusses the two methods for suppression of. multiple waves, namely, coherence emphasis method and twodimensionalfiltering method.
本文论述了两种消去多次波的处理方法。即相干加强方法和二维滤波方法。

Improvement to the old method formulated in this paper mainly lies in the combination of phase displacement method with frequency two-dimensionalfiltering in making operation.
本文对原方法的主要改进点是把相位移法与频率域二维滤波结合在一起进行运算。

The main points of this paper were- the table of the phase-shift factors, the variation of the continuation step length and the technique of the two-dimensionalfiltering.
