%X For the in-orbit calibration of HY-2 Satellite Radar Altimeter (ALT),three active transponders were developed by Mirslab,CSSAR,CAS,and the schemes and algorithms are designed for fulfilling the calibration requirements.Based on the system design and calibration rationales of HY-2 ALT and the transponders,the echo waveforms and trajectory's presented in the altimeter range window were simulated,and the calibration performance were also evaluated.Besides,the waveform features with multiple transponders are simulated to optimize their deployments.
