摘要 在阈值法的基础上提出了一种新的波形重跟踪算法——改进阈值法;采用Envisat数据计算,从数据利用率及距离改正标准差两方面,根据波形宽度分区对阈值法、OCOG以及Beta-5等3种算法作了比较,证实了改进阈值法在南极区域更为有效。 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.
