Abstract :
Numerical comparisons between radial basis function neural networks (RBFNN) and the linearly constrained least square method (LCLSM) are investigated for azimuth plane beamsteering of an array of axial sources about a PEC circular cylinder. The results show reasonably good agreement in pattern predictions for the two cases. The preliminary results suggest that the RBFNN can be a promising technique for practical realization of digital beamforming for adaptive, phased arrays on conformal surfaces
