摘要
This paper examines an improved median filter method. This method makes the filter effect of the (L-1)/2 sampling points on the boundary be same as that of the traditional median filtering,and makes the traditional filter results add in the improved median filtering. The wave field separation is done to the two zero-offset VSP cases and the result is compared with the wave field obtained by the traditional median filter.The comparison show that the improved median filter has high stiffness and adaptability relatively to the traditional one.
