摘　　要：作为星载雷达发射微波功率合成的关键部件,巴特勒矩阵的微放电性能直接决定了雷达载荷的功率容量。因此,有必要对其微放电特性进行分析与验证。针对该需求,提出了一种用于大功率动态合成网络的星载巴特勒矩阵,并对其在真空条件下的微放电特性进行了分析与验证。第一,提出了一款用于星载雷达的大功率巴特勒矩阵,对其功率合成性能进行了分析。第二,为了对巴特勒矩阵微放电性能进行详细研究,对提出的巴特勒矩阵进行了微放电功率阈值仿真和自由电子分布分析。第三,为了验证分析结果的正确性,对该巴特勒矩阵进行了峰值功率14 kW的真空微放电试验,验证了其在大功率真空环境下的微波传输功率容量。提出的巴特勒矩阵性能优良,为未来的星载雷达大功率微波部件提供了理论方法和关键技术支持。As a key component of microwave power synthesis for spaceborne radar,the multipactor performance of the Butler matrix directly determines the power capacity of the radar payload.Therefore,it is necessary to analyze and verify its multipactor characteristics.In response to this requirement,this paper innovatively proposes a spaceborne Butler matrix for high-power dynamic synthesis network,and then analyzes and verifies its multipactor characteristics under the vacuum condition.The following research is carried in this paper.First,this paper proposes a high-power Butler matrix for spaceborne radar,and analyzes its power synthesis performance.Second,in order to study the multipactor performance of the Butler matrix in detail,this paper carries out the multipactor power threshold simulation and free electron distribution analysis for the proposed Butler matrix.Third,in order to verify the correctness of the analysis results,this paper conducts a multipactor test with a peak power of 14 kW,which verifies its microwave transmission power capacity in a high-power vacuum environment.The Butler matrix proposed in this paper has excellent performance,and provides theoretical methods and key technical support for future spaceborne radar high-power microwave components.
