From Array Theory to Shared Aperture Arrays

Good judgment comes from experience; experience comes from bad judgment.

Walter Wriston, CEO Citybank

In this chapter we shall erect the theoretical infrastructure that will allow us to characterize a number of arrays in terms of their topology and the essential characteristics of their RF subsystems. Array theory is shared by all array systems and the analysis of several arrays constitutes a first step toward the derivation of synthesis procedures for arrays having prescribed characteristics. Real world considerations that enable the designer to come one step closer to the realization of arrays are also delineated.

The marginalization of the array sidelobe and grating lobe levels, a central issue ...
