Accurate Analysis of JEM Interference In Airborne Array Characteristics using Parallel HO-IE-DDM

In this paper, we present a parallel integral equations based on domain decomposition method discretized by higher-order basis functions (HO-IE-DDM) to analyze airborne array interference problems affected by jet engine modulation. This paper proposes two main novelties. Firstly, the interfered radiation characteristics of airborne array by multiple rotating blades are analyzed using integrated simulation technology. Secondly, the recalculation amount is reduced by using HO-IE-DDM, for only re-computing the changed parts of the model during the analysis process. Numerical examples with complex electrically large structures are simulating to demonstrate the flexibility, accuracy, and efficiency of HO-IE-DDM. The compared maps show the change laws of modulation level.
