Abstract :
The proposed approach is being developed in the framework of compact direction-finding systems that include polarization estimation. This work concentrates on sectorially symmetrical arrays, and combines the classical Array Scanning Method (ASM) with a Spherical Waves Decomposition (SWD) in order to directly compute the SWD coefficients based on the ASM current distributions. This approach offers the advantages of a fast computation based on the current distribution on only one antenna, as well as a reduced set of parameters needed to evaluate the embedded element patterns.
