Abstract

Abstract

A parallel higher-order and out-of-core based Domain Decomposition Method (DDM) is proposed for analyzing the disturbed characteristics of large airborne phased radar antenna array. When the phase of main beam sweeps for the airborne phased radar antenna array, the problem is divided into two parts: radar antenna array and airborne platform. The platform which remains unchanged during the overall solution is simulated only once at the beginning, and then the relative data, such as impedance matrixes are written into hard disk using out-of-core technique. When the phase sweeps, only the phased antenna array part is concerned. Finally, the accurate results are obtained by iterative solution. This method largely reduces the CPU time and storage requirements. The numerical example demonstrates that the proposed method is very suitable for analyzing the layout of large airborne phased radar antenna array.
