波束控制系统是相控阵雷达的一个重要组成部分，面对具有数千个天线单元的阵面，波控方案的选择尤为重要，它关系到系统的工作速度、性能指标、重量、功耗以及可靠性等诸多方面。根据多年的设计经验，结合相关领域的最新发展，给出了两种基于SOPC的相控阵雷达波控系统设计方案，并分别指出其优、缺点。

The beam-steering system is a very important component of the phased array radar.For an phased array radar antenna consisted of thousands of elements,the beam-steering scheme affects the working speed of the system,the performance,the weight,the consumption of electric energy,reliability and so on,so it is especially crucial.According to accumulated design experience over the years and combining with the latest development in related fields,this paper presents two schemes of beam-steering system of phased array radar based on the SOPC(System on a Programmable Chip),and points out both the merits and drawbacks.
