提出基于高频算法的求解相控阵天线近场的快速求解方案。建立相控阵天线子阵列模型,成功应用有源单元法获取单个阵元在考虑耦合情况下的方向图特性数据。给出镜像源法在多三角面片上的射线寻径的实现方法,并成功获取了射线路径。提出基于面片的实时空间区域二分算法的射线寻径加速方法,加速射线寻径过程,提升了程序计算效能,能够快速获取较精确的相控阵天线近场。
This paper proposed the resolution to get near-field of phased array based on high frequency algorithm.The subset of phased array is modeled to obtain the pattern characteristics of single element with taking the coupling into consideration which used the active pattern method. Image source method on the muti-facets was given to get the route of reflected ray. The paper also proposed the real-time spatial region bipartite accelerated method based on facets to accelerate the ray routing process and enhance the effectiveness of the program calculates. The near-field of phased array antenna can be obtained with relatively high accuracy using the resolution.
