| 摘 要： | 为同时满足对方向性系数,阵列效率,方向图旁瓣等参数的要求,提出了一种效率和旁瓣约束下的最优方向性综合法.该方法适用于任意的阵列形式,以最大化阵列方向性系数为目标,通过对加权向量的二次约束控制了阵列效率,并采用迭代的方法满足了方向图旁瓣的要求,实现了阵列效率和旁瓣约束下的方向性系数最优化.对多种阵列在不同要求下的仿真结果以及5元圆阵列的实验结果表明了这种方法的有效性和灵活性.

| Abstract: | In order to satisfy the requirement on array directivity, array efficiency and sidelobe level at the same time, a new pattern synthesis method is presented. Array efficiency is restricted to be higher than a given value by incorporating a quadratic inequality constraint on the weight vector, and the desired sidelobe level is achieved by implementing linear constraints through iteration. By optimizing array directivity subiect to efficiency and sidelobe constraints, the highest possible directivity with controlled array efficiency and desired sidelobe level is achieved. This method can be applied to arbitrary array geometries. The simulation results of different arrays and experiment on 5 element circular array demonstrate the validity and flexibility of this proposed method. |
