Caiyun Wang, Wei Guo, Peng Liu, Te Wang · 2020
An improved transponder for HY-2B (Haiyang) radar altimeter is presented in this paper. HY-2B is the follow-on mission to HY-2A, the Chinese sea satellites for oceanography. An improved transponder was developed. It has some advantages over the HY-2A one. The paper describes the development and integration test of the transponder. Some new techniques are employed. Its performance is stable and qualified for HY-2B altimeter calibration.
