GUO Wei, ZHANG Xiao-hui. Development of return signal simulator for chinese satellite altimeter prelaunch performance assessment[J]. Editorial Office of Optics and Precision Engineering, 2004,(4): 359-366DOI:
An ocean Return Signal Simulator(RSS)and the principles of the RSS with its means of testing and calibrating for a satellite altimeter were given. By using the chirp regeneration technique
full de-ramp technique
ocean return spectrum digitally synthesizing technique and high speed DSP technique
a full signal RSS was successfully developed for a Chinese satellite altimeter test and calibration
full range of time delay and full sea state simulation were achieved. Time delay precision is(0.2)ns
significant wave height(SWH)simulation precision 0.5 m and backscattered coefficient precision 1 dB. By using the RSS
the full system testing and calibrating experiment to the Chinese satellite altimeter were implemented. The results show the dynamic performance of the RSS and the altimeter are validated.
