相控阵雷达天线模型及仿真

内容简介：阐述了相控阵天线仿真的重要性，指出了相控阵天线仿真的主要困难。提出了一种利用阵因子、方向性因子和旁瓣抑制因子分别解决仿真波束形状、天线增益、方向图旁瓣及其变化等3大问题，并进行综合建模和仿真，给出了综合后的仿真模型。该仿真模型保证了理论方面的精度，优化和减少了仿真计算步骤和计算量。利用该仿真模型，给出了宙斯盾系统的AN/SPY-1D雷达天线的仿真计算实例。

Abstract：The importance and the main difficulty of simulation of phased array antenna were given. And a modeling and simulating method was proposed. This method used array factor, directional factor and sidelobe suppression factor to re-spectively resolve the problems of beam configurations, antenna gain and the sidelobe and its change of directional dia-gram, and then synthesized. The simulation model after synthesizing was given. This simulation model ensured the theoreti-cal precision, optimized and reduced the steps and quantities of simulating calculations. Using the simulation model, a sim-ulation calculation instance of the radar antenna of AN/SPY-1D of Aegis system was given.
