摘要 给出了圆形阵列方向图综合的数值计算方法,对圆形阵列方向图综合以及零点形成进行了分析和研究,以参考方向图与综合后方向图之间的距离最小化为准则,通过数值分析方法,在无约束和干扰零点约束情况下,给出了相应的最优权的求解方法,仿真分析表明了该方法的有效性. A new numerical synthesis algorithm is presented for circular arrays, and the synthesis algorithm is analyzed and researched. According to optimization rule of the minimum of mean-square distance between a reference pattern and synthesized pattern, the relevant optimum weighted vectors are obtained by numerical pattern synthesis algorithm in case of non-constrained or null-constrained. Analysis and simulations show that the algorithm is efficient. 7figs., 8refs.
