Interpolation Based Radiation Pattern Correction in Conformal Beamforming Arrays

This paper presents a low complexity pattern recovery method for a strongly deformed conformal phased-array based on Linear Pattern Correction Method (LPCM) by using pre-stored individual antenna radiation patterns. In order to reduce the storage requirements, the radiation patterns of wedge dipole arrays considered in this work, have been taken at certain deformation factor and the rest of the patterns are obtained through interpolation. Comprehensive analysis of pattern recovery using desired and interpolated patterns show good recovery of radiation pattern with the position of the nulls and the main lobe restored. Mean Square Error (MSE) and Nulls depth comparison for pattern recovery using interpolated patterns is also investigated.
