| Abstract(in English) | The calibration of the SAR data acquired by JERS-1 satellite is very important to forward the earth monitoring,because the SAR data can be directly related to the backscattering coefficient of the ground surface without the consideration of air condition. While the absolute calibration of the SAR data can be achived by deploying the corner reflectors,the Monte Carlo Simulation was conducted to estimate the relationship between saturation rate of the raw data and its calibration results.As a result,it was found that the calibration result was not affected by the saturated components of the SAR image even its rate is 3 - 5 %,and SAR correlated power is linearly related to the input power within the dynamic range of the AD converter.However,the intensity imballance appreaed at the shore area in SAR image should be discussed future in more detail. |
