Abstract : The array theorem is investigated by considering mutual coherence. It is first treated under the conditions of monochromatic illumination followed by a development of a generalized array theorem using the mutual coherence function. The coherent limits are imposed upon the radiation with the following results. In the incoherent limit and under the restriction of uniformly illuminated, in-phase antennas it is seen that the array theorem gives the mutual intensity in the field. In the coherent limit the array theorem holds in general but in the partially coherent case, no separable form for mutual coherence function was available. (Author)
