| Abstract: | In the paper, the scattering mechanism of the ocean return signals from the spaceborne ocean altimeter and the backscattering model of the return signals were briefly described; By means of the Matlab tool, the Altimeter's IQ sampling data were isolated from a mass of scientific data received by the "SZ-4" Spaceship, and the statistical characteristic of the ocean return signals from the Multi-Mode Microwave Remote Sensor (M3RS) Altimeter was analyzed by way of data processing and statistical analysis of the IQ sampling data. |
