介绍了卫星雷达高度计回波波形形成原理,并对Jason-1卫星经过中国南海海域的回波波形进行了分析。分析结果说明在近海海域的部分回波波形受到地形严重影响,需要通过波形重构进行误差修正。
The formation principle of satellite radar altimeter echo waveform is introduced, and the echo waveform of Jason-1 satellite passing the South China Sea area is analyzed. The analysis results show that some echo waveforms in the offshore area are severely affected by the terrain, and the error correction needs to be performed through waveform reconstruction.
