A universal technique is proposed for the analysis of the noise temperature of an arbitrary phased antenna array allowing to estimate the contribution of all the sources of internal noises under rigorous taking into account of the mutual coupling between loss radiators. The technique is based on the matrix theory of antenna arrays [1, 2] and noisy microwave multiport circuits theory [3, 4].References
