摘要
该文在分析圆阵波束指向性的基础上,提出了一种改善圆阵波束指向性性能的对称指数加权方法,利用该方法能较有效地抑制旁瓣,而主瓣的增宽效应并不明显.
Based on the analysis of the directivity of the circular array, a symmetrical exponential weighting method which improves the directivity of the circular array is developed in this paper. Using this method, the sidelobe level can be efficiently rejected and the mainlobe width be little widened.
