也有效验证了一种卫星高度计的动态工作性能.

Abstract

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.
