通过模型资料测试，以及近地表反射地震实例叠前资料面波压制试处理研究工作，验证了多线束径向中值滤波方法的可行性和实用性。

The feasibility and effective of the multi-radial mid-value filtering have been verified through some model data tests and suppressing the surface wave in the practical pre-stack seismic data.

反射波在经过近地表的过程中受到诸多因素的干扰，尤其是地表起伏和近地表低降速带，对其影响甚大。

Reflections are impaired by interferences, especially irregular topography and low velocity layer when they travel through near surface.
