基于OpenMP的多辐射源二维电波传播预测方法

Approach for modeling 2-D radio wave propagation of multi radiation sources based on OpenMP

复杂电磁环境是当前仿真领域的热门研究问题,而多辐射源是构成复杂电磁环境的重要因素之一.传统抛物方程方法需通过多次计算以得到所有辐射源的电波传播特性,效率低下且执行繁琐.为克服该不足,提出了基于OpenMP(Open Multi Processing)的抛物方程并行计算方案.该并行方案可充分利用计算机资源,实现高效模拟多种辐射源在大尺度复杂环境中的电波传播.仿真计算表明,该并行方法可大幅提升计算速度且具有较高的并行计算效率.

Complex electromagnetic environment is the hot research topic in the field of simulation and multi radiation sources is one of the most import ant ele-ments. The traditional parabolic equation model should be calculated several times to get the electromagnetic informations of all radiation sources, which would cost excessive computation time. For that, a parallel programming of parabolic equation model based on Open Multi Processing （OpenMP） is proposed, which can model radio wave propagation of multi radiation sources in large computing space efficient-ly by making full use of the multi-core computer. The numerical simulation demon-strates that the parallel programming markedly improves the computing speed and achieves high parallel computing efficiency.
