摘要:

介绍了通过Matlab/Simulink建立干涉式微波辐射计系统仿真模型的方法。针对干涉式微波辐射计的基本构成单元——二元干涉仪,搭建了仿真模型,通过对辐射计随机噪声测量过程的模拟,实现了单通道全功率测量仿真及双通道干涉测量仿真,在时域范围内实现了对系统测量精度、灵敏度指标的定量化分析。

关键词: 干涉式微波辐射计可见度函数仿真模型Simulink    
Abstract:

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.

Key words: Microwave interferometric radiometer    Visibility function    Simulation model    Simulink
