This thesis mainly discuss following issues, Theory and simple expressions for array covariance matrixes are derived when angular spread functions are symmetric distribution functions, i. e. the Uniform distribution, the Gauss distribution, the Laplace distribution and the Von Mises distribution, and a non-symmetric distribution function, i. e. the Gamma distribution. And the relation between the effective signal subspace and the array number, or and the nominal angle of the distributed source, the angular spread, the distributed functions, and the Signal-to-Noise Ratio is gained. The dimension of the effective signal subspace increases with increment of the array number. And it is more obvious to the non-symmetric distribution. The dimension of the effective signal subspace decreases with increment of the nominal angle. And the distributed source is equal to a point source as θ=π/2. The dimension of the effective signal subspace increases with increment of the angular spread.

本论文针对阵列信号处理中广泛存在的分布源现象,主要讨论了以下问题:推导了角度分布函数分别为对称的均匀分布、高斯分布、拉普拉斯分布、Von Mises分布和非对称的伽马分布时,分布源阵列接收信号协方差阵的严格模型和简化模型,得到了单个分布源的有效信号子空间随阵元数、分布源中心角、分布角、角度分布函数和信噪比的变化规律:随着阵元数的增加,对所有角度分布函数的有效信号子空间维数也随着增加,且非对称分布函数的有效信号子空间充满整个空间的可能性更大;随着分布源中心角逐步增加,有效信号子空间维数逐步减小,当θ=π/2时,等价于点源情形;随着分布源分布角逐渐加大,有效信号子空间维数也随之增加,直到有效信号子空间充满整个空间;随着信噪比的增加,有效信号子空间维数有一定程度的减少。
