摘要:

全极化微波辐射计是未来星载遥感海面风场的重要微波遥感仪器,可为短期天气预报、气候学和海洋学研究提供重要的有价值信息,利用软件平台对全极化辐射计进行计算机仿真对于系统设计和全极化定标技术仿真验证具有重要的意义。对X波段相关型全极化微波辐射计进行了计算机仿真,基于ADS软件平台建立了相关型全极化微波辐射计系统仿真模型,对仿真模型有效性进行了验证,并在仿真模型基础上对全极化定标技术进行了仿真验证。结果表明仿真模型准确有效,可为系统设计和全极化定标仿真验证提供参考。

Abstract:

Fully polarized microwave radiometer plays an important role in remotely sensing sea surface wind vector from space in the future,and it can provide crucial valuble information for short-term weather forecast,meteorological and oceanographic studies.Fully polarized radiometer's simulation based on computer software platform is significant for system design and fully polarized calibration method simulation validation.System simulation model of polarization-correlating microwave radiometer is established by ADS software,and then its effectiveness used for fully polarized calibration method is validated in terms of the relationship between input stokes vector and output voltage vector.Based on the system model,calibration method of fully polarized calibration standard is validated via noise injection method.Simulation results show that the system simulation model is valid and can be served as a reference for system design and fully polarized calibration method simulation validation.

Key words: Fully polarized radiometer    Stokes parameter    Computer simulation
