| Abstract: | Based on the working principle of suboptimal maximum likelihood estimate system and tracking control requirements in ocean altimeter on satellite,a new suboptimal maximum likelihood estimate system is designed.With full consideration of height tracking,slope tracking and automatic gain control,the altimeter opration can be effecfively controlled and a high measurement accuracy of various parameters is obtained. |
