相控阵雷达多通道天线方向图建模与仿真

内容简介：相控阵雷达天线方向图建模是相控阵雷达系统建模仿真中的关键技术之一。本文从理论上分析了天线方向图函数，提出了一种相控阵雷达多通道天线方向图建模与仿真算法。基于相控阵天线的矩形平面模型，我们通过配置不同的天线阵元矩阵参数，最终获得了不同通道的天线方向图。文中的算法不仅能够较为便捷地获取常规的和差通道天线方向图，而且能够获取其它任意通道天线方向图。仿真结果验证了建模方法和数学模型的正确性。

Abstract：Antenna pattern modeling for phased array radar is one of the key technologies in modeling and simulation for phased array radar systems. In this paper,we analyze the antenna pattern function theoretically,and propose a modeling and simulation algorithm in multi-channel antenna pattern for phased array radar. Based on rectangular planar model of phased array radar,we get the antenna pattern in different channels by configuring different matrix parameters of antenna array elements. Using this algorithm, we not only obtain sum-difference channel antenna pattern easily, but also get antenna pattern in any other channels. The simulation result shows that the modeling method and mathematical models are right.
