Abstract
Classical near field to far field transformation algorithms are unable to deal with irregularly distributed measurement samples. As frequency increases, this may be a serious limitation in certain scenarios. In this paper a near field to far field transformation algorithm that works with samples over arbitrary measurement surfaces is investigated. The approach is based on the modeling of the measured fields using a spherical wave expansion. The spherical modes are obtained solving a linear system of equations using an iterative method. The algorithm is validated using analytical antenna models, showing controllable transformation errors. To reduce the computation time of the iterative solver, a matrix preconditioner implemented by means of a fast operator is presented.
