The paper briefly introduces absolute calibration methods of sea surface height and backscatter of satellite altimeter.

The effects to height evaluation of the main noises, i.e. ocean surface backscatter speckle noise and receiver thermal noise, are analyzed. By analyzing the returned signals of several typical sea states, the results have shown that the system height measurement precision can be ± 2cm.

分析了主要噪声，即海面斑点噪声和接收机热噪声对高度估值的影响，通过对几种典型海况海面回波的模拟分析表明，系统则高精度可达±2cm。
