星载海洋雷达高度计信号处理实时仿真

The Real time Signal Processing Simulation for Spaceborne Ocean Radar Altimete

简要地介绍了海洋雷达高度计的基本原理，分析了最大似然算法在星载雷达高度计信号处理中的应用，研制出了中频回波模拟器，利用该仪器对准最大似然算法进行了实时仿真研究。

In this paper, the chief principle of the ocean radar altimeter (RA) is briefly introduced. The real time simulation experiment of the quasi maximum likelihood emulation is successful through the IF simulator, which is implemented by digital signal processor and can generate realistic return waveforms.
