A Simulation Study on Waveform Model and Performance Evaluation for an Altimeter Transponder System
星载雷达高度计有源定标器回波模型及性能仿真研究

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.
