摘　　要：描述实际散射体散射特性的散射矩阵一般是时间的函数。因此,即使入射电磁波是完全极化电磁波,散射电磁波也不再是完全极化电磁波,而是部分极化电磁波。本文讨论了对部分极化电磁波的最佳接收问题,并给出计算天线接收功率的简化算法。The scattering matrix, which describes the scattering property of practical scatters, is generally a function of time. So, the scattered electromagnetic wave is no longer a completely polarized wave, but a partially polarized wave, although the incident wave is completely polarized. This paper mainly focuses on the optimal reception of partially polarized electromagnetic wave, and derives the method for optimizing the intensity received by the antenna.
