Abstract
Wiener inverse filter is one of the deconvolution means to renew echo for improving vertical resolution. It is argued that the traditional algorithm is not stable, presents a modified means to improve this problem based on difference test systems, that is use different coefficient for correspondence range, and spectrum extrapolation method. An experiment has proved this modified means is feasible.
