| 摘 要： | 提出了一种基于最小干扰抑制比技术的线阵几何设计方法,它不同于传统的等间距设计方法.首先提出一个干扰抑制比的概念,并基于此构造了一个非线性代价函数,利用最速下降法,通过最小化该代价函数,求得线阵几何的最优解.仿真表明,该方法可以大大改善天线阵列的干扰抑制能力,降低旁瓣水平,减小主瓣宽度,增加阵列孔径.

| Abstract: | Based on the minimum interference suppression ratio,the paper presents a design method for linear array geometry,which is different from the conventional equispaced linear array. The concept of interference suppression ratio is proposed. Based on the concept,a cost function is constructed. The optimum solution of linear array geometry is obtained by minimizing the cost function with steepest descent method. Simulation results show that the method proposed can greatly improve the capability of interference suppression,decrease the sidelobe level,reduce the mainbeam width,and increase the array aperture. |
