星载极化相关型全极化微波辐射计是一种新型空间被动微波遥感仪器, 为海面风场等海洋大气环境参数的遥感探测提供了重要技术途径. 天线交叉极化校正是其数据预处理算法的重要环节. 本文针对星载极化相关型全极化微波辐射计天线交叉极化校正需求, 以极化相干检测理论为基础, 结合Stokes参数的定义, 自主推导了其适用的全极化天线温度方程. 该方程针对四个Stokes参数天线温度, 引入了Stokes参数之间交叉极化的振幅和相位, 并考虑了极化旋转角对天线方向图计算的影响. 最后, 建立了天线扫描波束与地球场景的几何对应关系, 对天线温度方程中各参数的确定方法进行了探讨. 全极化天线温度方程的建立为进一步开展星载极化相关型全极化微波辐射计天线交叉极化校正奠定了基础.Spaceborne polarimetric microwave correlation radiometer is a new type of instrument for the passive microwave remote sensing from space, which can provide an important way for remote sensing of sea surface wind vector and other ocean atmosphere environmental parameters. Antenna cross-polarization correction is an important part of the data pre-processing algorithm. In this paper, for the demand of antenna cross-polarization correction in spaceborne polarimetric microwave correlation radiometer, we have independently derived the full polarization antenna temperature equation based on the polarization coherent detection theory and the definition of Stokes parameters. The equation for the four parameters of Stokes antenna temperature introduced the cross polarization amplitude and phase between the Stokes parameters. Besides, the influence of the polarization rotation angle on the antenna pattern computation was considered. Finally, we established a geometric correspondence between the antenna scanning beam and the earth scene. The principle for determining the parameters of the antenna temperature equation was also discussed. Stokes antenna temperature equation laid the foundation for antenna cross-polarization correction for spaceborne polarimetric microwave correlation radiometer in the future.
