Development and Pre-Launch Test of a Return Signal Simulator for HY-2B Altimeter
Wei Guo, Caiyun Wang, Peng Liu · 2018
A return signal simulator (RSS) for HY-2B altimeter is described in the paper. HY-2 is the second one of China's serial oceanic remote sensing satellites, which purpose is for ocean dynamic parameter measurement. The main payload on board to measure the sea surface height is a dual frequency altimeter. In order to test and calibrate the altimeter before its launch, a RSS is developed and a series of tests are performed. The RSS could generate simulated echoes of sea surface with accurate time delay and flexible power, therefore provides thoroughly test and function validation for the altimeter. The RSS's development and integration, pre-launch test and function verification to the altimeter are presented in this paper.
