In this paper the PTR and LPF of China’s HY-2A satellite altimeter were extracted and their features were analyzed. Then Look-Up Tables (LUTs) of the range (height), SWH and amplitude (AGC) were generated based on the PTR and LPF by Monte-Carlo simulation. The actual PTR and the Bessel FSIR expression were included in the simulation model to acquire the(More)
A transponder system is developed to fulfill the inorbit calibration of the HY-2 satellite altimeter (ALT) and scatterometer (SCAT). The interaction of a calibration transponder and radar (altimeter / scatterometer) is rather complicated. After a brief description of the two active payloads on HY-2 satellite, several key issues are investigated in detail,(More)
