Abstract

In 1978 Lohmann and Rhodes [1] presented a general two-channel hybrid system for bipolar incoherent spatial filtering. The work by Lohmann and Rhodes was significant in that it presented a unified and compact analysis of such filtering. However, of equal importance is a consideration of synthesis, or design. With respect to bipolar synthesis, two issues must be addressed; one, the feasibility of the synthesis and two, the specification of the system once its feasibility has been established. It is the question of feasibility or, in mathematical terms, existence, that is addressed in this work; the issue of system specification is presented in Ref. [2].
