【Abstract】 In this paper,the covariance matrix and covariance coefficient of antenna receiving signals is derived from the distribution of incoming waves and the antenna patterns. The implication of some physical quantity is interpreted. The relationship of the antenna parameters,covariance matrix,covariance coefficient and the performance of diversity in different distribution of space fields is analyzed. This paper has some theoretical significance to the calculation of the covariance matrix and the covariance coefficient of antennas.更多还原
