在线性阵列天线方向图正交综合法基础上实现有零点约束的方向图综合。正交综合法对阵元结构和类型都没有特殊要求,具有很强的通用性。在此基础上使用拉格朗日乘数法实现零点约束条件下的线阵方向图综合。仿真结果表明:只通过简单的解析计算的方法就能很好实现零点约束方向图,证明了此方法的有效性。 On the Basis of Orthogonal Synthesis of Linear Array Antenna Pattern, Realization of Pattern Synthesis with Zero Constraints. Orthogonal Synthesis of elements and structure of the array are no special requirements, has a strong versatility. On this basis, Lagrange multiplier method is used to realize the synthesis of the line pattern under zero constraint condition. The simulation results show that the method of zero constraint can be well implemented only by a simple analytical calculation method, and the validity of this method is proved.
