射线追踪法是计算有等离子体包覆的飞行器电磁散射特性的经典方法,计算效率较低是制约该方法应用的主要因素,如何高效的利用现代计算机技术和射线追踪计算模型已经成为电磁散射计算的一个重要发展方向。拥有多内核CPU的计算机的出现和流行为提高射线追踪法计算在等离子体包覆下的飞行器电磁散射特性的效率提供了一个有效地途径。在共享存储(OpenMP)模型的基础上,对射线追踪法进行分析,实现了对射线追踪法并行计算的编程,并有效地提高了射线追踪法的计算效率。
Ray tracing method is a classic method to calculate the electromagnetic scattering characteristics of plasma-covered aircraft. The low calculation efficiency is the main factor restricting the application of this method. How to make efficient use of modern computer technology and ray tracing calculation model has become An important direction of development. The emergence and popularity of computers with multi-core CPUs provide an effective way to improve the efficiency of ray tracing in the calculation of the electromagnetic scattering properties of aircraft under plasma cladding. Based on the shared memory (OpenMP) model, the ray tracing method is analyzed, and the parallel computing of ray tracing method is programmed, and the computational efficiency of the ray tracing method is effectively improved.
