中文摘要：
基于共线平差方法，比较了同步运行段Jason-1两种观测数据和T／P观测数据的有效波高、后向散射系数、各项地球物理改正以及改正后的海面高，解算比较了两颗卫星的各自单星交叉点不符值。计算结果验证了Jason-1测高卫星具有与T／P卫星相当的实际观测精度，能够较好地延续T／P卫星任务。
英文摘要：
The significant wave height, backscatter coefficient, geophysical corrections and corrected sea surface height of two version of Jason-1 data are compared with synchronous T/P data based on collinear method. Single satellite crossover differences of Jason-1 to T/P are also calculated and compared. The results show that Jason- 1 altimetric data have the equivalent accuracy with T/P, so it can be a good substitute of T/P and realize the first 20 year period observations together.
