Abstract:

The present status of the space-based radar phased array lens simulator is discussed. Huge arrays of thin wire radiating elements on either side of a ground screen are modeled by the simulator. Also modeled are amplitude and phase adjust modules connecting radiating elements between arrays, feedline to radiator mismatch, and lens warping. A successive approximation method is employed. The first approximation is based on a plane wave expansion infinite array moment method especially suited to large array analysis. the first approximation results then facilitate higher approximation computations that account for effects of nonuniform periodicities lens edge, lens section interfaces, failed modules, etc.. The programming to date is discussed via flow diagrams. An improved theory is presented in a consolidated development. the use of the simulator is illustrated by computing active impedances and radiating element current distributions for infinite planar arrays of straight and swept back dipoles arms inclined with respect to the array plane with feedline scattering taken into account.
