Abstract An improved threshold retracker based on the threshold method is put forward. Using Envisat data, three methods(threshold retracking method，OCOG method and Beta five method) are compared in two aspects——the success rate of retracking and the standard deviation of retracked distance according to the waveform width, it can be verificated that the improved threshold method is more effective in the Antarctic area.
