Abstract

We analyze statistical properties of resolving two signal sources with plane wavefronts via eigenvalue analysis of the sample correlation matrix of the intrinsic noise of the receiving system for a low signal-to-noise ratio. The analysis was carried out both for the signals of the same power and in the presence of a single high-power interference source. The resolution properties of two sources with different signal arrival angles are also considered. The distribution of the maximum noise eigenvalue in the presence of a weak signal source is studied numerically.
