The improved design for HY-2B radar altimeter

HY-2B, the second China's satellite for oceanic dynamic environment measurement, is scheduled to launch at 2018. To improve the capability, some new methods are adopted in HY-2B altimeter design. By these means, the long term stability of the instrument is improved compared with HY-2A altimeter. In this paper, the improved design based on a rubidium atomic clock for HY-2B altimeter is discussed in detail.
