The main idea of reassignment method in time-frequency analysis is presented and some expressions used to compute the accurate location of the local energy gravity center are given;then two numerical experiments are presented to show how these reassignment methods work individually as used to process single-trace seismic data.Based on the experiments,some conclusions are drawn that the reassignment methods can not only effectively reduce cross-terms,but also lead to a good time-frequency concentration.Compa...
