摘要: 在抗干扰阵列天线小型化的基础上,提出了一种波束形成的新技术.在实际设计中,通过减小阵列天线单元之间的间距实现了阵列天线的小型化;编制高频结构仿真VBScript脚本程序来提取阵元的有源方向图和有源阻抗数据;在Matlab中编写了基于差分进化算法的优化设计程序;通过Matlab来调用高频结构仿真进行全波仿真分析,得出最优的阵元加权因子以实现抗干扰阵列天线的波束零陷.研究结果表明,该技术能够非常精准地在干扰方向(30°,10°)上形成零陷,且零陷深度提高了32dB.

Abstract: Based on the miniaturization of the anti-jamming array antenna, a new technique for beamforming is proposed. In the actual design, the array antenna is miniaturized by reducing the spacing between array antenna elements; the HFSS VBScript script is programmed to extract the active pattern and active impedance data of array elements; the optimization based on the differential evolution algorithm is written in Matlab; HFSS is called by Matlab for full-wave simulation analysis, and the optimal element weighting factors are obtained to achieve the pattern null of the anti-jamming array antenna. Research results show that this technique can form pattern null in the interference direction (30°,10°)very accurately, and that the null depth  increases by 32dB.


Key words: anti-jamming antenna array, miniaturization, beamforming, differential evolution algorithm
