摘要:

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 respectively resolve the problems of beam configurations, antenna gain and the sidelobe and its change of directional diagram, and then synthesized. The simulation model after synthesizing was given. This simulation model ensured the theoretical precision, optimized and reduced the steps and quantities of simulating calculations. Using the simulation model, a simulation calculation instance of the radar antenna of AN/SPY-1D of Aegis system was given.
