Abstract

Resolving electromagnetic (EM) signals in both polarization and space domains is investigated based on polarization sensitive array (PSA). The resolution theory of PSA signals is brought forth, which parallels the resolution theory of radar signals. Novel concept of the ambiguity degree function of PSA signals is proposed and expressed in close form, depending on their polarization angles and arrival angles. The ambiguity degree function predicts whether two EM signals can be resolved or not. Two signals cannot be resolved when they come from exactly the same direction. However, the polarization discrimination can improve the resolving power
