A method using Simulink to build the simulation model of the microwave interferometric radiometer(MIR)system is introduced in this paper.Two-element interferometer is the basic unit of the MIR system. By the Simulink platform,a simulation model of the two-element interferometer was built and the measurement process of the random noise was simulated.Through the simulation of the full power measurement achieved interference measurement of single channel and two channels.Quantitative analysis of the radiometric accuracy and radiometric sensitivity were achieved in the time domain. |
