We propose a new method to discretize a 2D panel radiating over a prescribed Quiet-Plane (QP) as a nonuniform array. Since the most significant singular functions of the radiation operator supported on the panel are linked to those supported on the QP by means of a radiation integral, a Gaussian quadrature rule is exploited to replace the integrals with weighted summations. The quadrature provides a unique set of nodes, namely the array elements positions, and weights, which are involved in determining the excitation coefficients of the array. To avoid mutual couplings, a proper 'pruning' approach has been implemented. Numerical validation is also presented.

Abstract
We propose a new method to discretize a 2D panel radiating over a prescribed Quiet-Plane (QP) as a nonuniform array. Since the most significant singular functions of the radiation operator supported on the panel are linked to those supported on the QP by means of a radiation integral, a Gaussian quadrature rule is exploited to replace the integrals with weighted summations. The quadrature provides a unique set of nodes, namely the array elements positions, and weights, which are involved in determining the excitation coefficients of the array. To avoid mutual couplings, a proper 'pruning' approach has been implemented. Numerical validation is also presented.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
