摘　　要：针对多约束条件下稀布矩形平面阵列天线的优化问题,提出异法则矩阵映射方法,以获得更低的峰值旁瓣电平。该方法在现有矩阵映射方法的基础上,对矩形平面中不同方向的坐标定义不同的映射法则,以满足实际工程应用中的多个约束条件,将有约束优化问题转化为无约束优化问题。异法则矩阵映射方法可以改善现有方法随机性强和搜索精度低的不足,提高搜索效率。为检验该方法的可行性进行了仿真实验,实验结果表明该方法可以有效降低阵列天线的峰值旁瓣电平。To reduce peak sidelobe level in the synthesis of sparse rectangular planar arrays with multiple constraints,different-principles matrix mapping method is proposed in this paper.The method is modified on the basis of existing matrix mapping method,defining different mapping principles for two coordinates of two directions in the rectangular planar,which can meet the multiple constraints in practical engineering practice and transform the constrained optimization to the unconstrained optimization.The method can make up the deficiency of strong randomness and low searching precision,and improves searching efficiency.To test the effectiveness of the method,simulation experiments are conducted.The results demonstrate that the method can obtain lower peak sidelobe level of antenna arrays than existing matrix mapping method.
