Abstract

In this paper, we present a parallel integral equation solver based on domain decomposition method for the analysis of airborne array interference problems affected by jet engine modulation. The solver makes use of higher-order basis functions for the discretization of the problem. The paper proposes two main novelties: firstly, the radiation characteristics of the airborne array (interfered by multiple rotating blades) are analyzed using an integrated simulation technology; secondly, the computation during the analysis of JEM problem is significantly reduced, for only re-computing the changed parts of the model. Numerical examples using complex electrically large structures are presented in order to demonstrate the flexibility, accuracy, and efficiency of the proposed integral equation solver.
