HY-2A radar altimeter design and in flight results

Xu Ke,Liu Heguang,Jiang Jingshan

Strategic Study of CAE 2013, Volume 15, Issue 7,   Pages 25-32

Abstract:

HY-2A is the first satellite for oceanic dynamic environment measurementAs one of main payloads of HY-2A, HY-2A radar altimeter has obtained successive measurement data afterThe accuracy of HY-2A radar altimeter is better than 4 cm (at 20 m significant wave height) or 2 cm (at 4 m significant wave height), which is close to that of Jason-2 satellite altimeter.In this paper, the design and in flight preliminary results of HY-2A radar altimeter are introduced.
