利用准最大似然估计算法，可以估计海洋卫星高度计中海平面到卫星平台之间的高度．本文首先讨论了最大似然算法的基本原理，然后根据高度计的测高原理，讨论了采用准最大似然估计带来的高度偏差，并提出了进行计算机仿真的有效方法，分析了均方根高度误差与信噪比、脉冲累积量和均方根波高之间的关系．
Using a quasi-maximum likelihood estimation algorithm, it is possible to estimate the altitude of the maritime satellite altimeter from the sea level to the satellite platform. In this paper, the basic principle of maximum likelihood algorithm is discussed first. Then according to altimeter altimeter theory, the height deviation caused by quasi-maximum likelihood estimation is discussed and an effective method for computer simulation is put forward. The root mean square height Relationship between error and signal-to-noise ratio, pulse cumulant and root mean square wave height.
