A new idea of the complex weighted array antennas in proposed. A generalized weighted factor is given. Also, the general formulae for calculating the element numbers, field patterns, power patterns and array efficiency of the complex weighted array antennas are derived. The application of the complex weighted array antennas will be advantageous to the reduction of costs, improvement of performences and system adaptability.

本文提出了复合加权阵列的概念,引入了具有普遍意义的随机阵列的广义权因子,导出了计算复合加权阵列天线的单元数目、场强方向图、功率方向图和加权效率等性能参数统计特性的普遍公式。大家所熟知的密度渐稀阵列和相位加权阵列均可归结为本文所提出的复合加权阵列的特例。应用复合加权阵列天线将会带来降低有效成本、提高性能及增加系统灵活性等好处。

Because of the globe economy and the market economy in our country, it has become the important problem how to increase productivity efficiency. Region productivity element fluxion is the microeconomic foundation in region economics. From the angle of regions cooperation and competition in the country, we realize the region productivity element's array and increasing array efficiency have important realistic meaning.

由于经济全球化和我国市场经济发展,充分发挥生产要素效率和调动生产要素积极性已成为难点问题。要素流动是区域经济这个中观经济问题的一个微观基础,与区域经济的非均衡发展有着密切的互为因果关系。从一国之内的区域合作与竞争角度研究要素流动,实现要素的区域优化配置,提高要素的配置效率,有重要的现实意义。

The existing pattern synthesis method can't be used for superdirective array antennas for they can't ensure the dominance of external noise as well as keep high array directivity.A new pattern synthesis method which can be applied to superdirective arrays is presented.It can also be applied to arbitrary array geometries.The dominance of external noise is ensured by constraining the array efficiency,and the desired sidelobe level is achieved by implementing linear constraints through iteration.By optimizing the array directivity subject to array efficiency and sidelobe constraints,the highest possible directivity with controlled array efficiency and desired sidelobe level is achieved,and the requirement on superdirective array synthesis is satisfied.The simulation results of different arrays show that the proposed method is very effective and flexible.

以往的阵列综合方法不能在获得高的方向性系数的同时保证外部噪声占优,不能用于超方向性阵列综合.本文提出了一种新的阵列综合方法,该方法适用于任意阵列形式,以最大化阵列方向性系数为目标,通过对阵列效率的约束保证了外部噪声占优的条件,并通过迭代控制了方向图的旁瓣,实现了阵列效率和旁瓣约束下的方向性系数最优化,很好地满足了超方向性阵列综合的要求.对多种阵列的综合结果表明了这种方法的有效性和灵活性.
