Abstract
Lateral spatial coherence of an antenna is modeled by random phase front tilts. An effective source coherence length is introduced, and a generalized Fresnel coefficient which takes into account the coherence of the source is abstracted. Generalized reciprocity relationships for beamwidth and source coherence as well as for observed coherence and source power distribution valid in the near and far field are developed
