Abstract
In order to optimize the spaceborne microwave scatterometers in China,a MATLAB software is utilized to set up a HY-2 microwave scatterometer simulation model.Firstly,the transmitter,receiver,and signal processing unit are simulated according to the preliminary design simulation model,and the final design plan and parameters.And then,for in-orbit sea surface observation process,the simulation model is divided into six parts,viz.:signal source,transmitter,sea surface echo signal,receiver,signal processing unit,and output.And the channel characteristics are taken into consideration in the preliminary state model to update the model.In the end,the radar equation is adopted to calculate the sea surface backscattering coefficient.The model is proved to be correct,and provides a simulation analysis method for the follow-on spaceborne microwave scatterometers design and optimization in China.关键词
