中文摘要：

根据“子阵列”理论，对星载阵列相控阵多波束天线的阵元空间和波束空间进行子阵分割，分析天线阵元空间成形系数的复用情况，并结合分布式算法，在阵列分解基础上提出了一种波束成形网络的复用结构，节省了67％以上的资源。最后实现了波束成形网络的试验验证平台，并完成了算法的移植和验证。结果表明，该波束成形网络比常规方法节省了大量资源，并实现了多波束等通量覆盖的设计目标。

英文摘要：

A practical scheme of array partition implemented on phased array antennas＇ beam space and element space was proposed based on the ＂sub-array＂ theory. The multiplex of beam forming coefficients between antennas＇ elements was analyzed. The distributed arithmetic algorithm was adopted to realize the beam forming network of phased array antennas. And a new multiplex structure of the beam forming network was proposed according to the array-partition＇ s results. Ultimately, a hardware platform of the beam fomling network was designed and implemented. The experiment result demonstrates that the consumption of the novel beam foaming network＇ s multiplier resource can be reduced to 33 %, which validates the feasibility of the design.
