摘　　要：该文采用S参数分析了有源相控阵天线单元馈电系统模型的接收机负载反射系数。将该反射系数代入阵列天线散射场基础理论公式分析了有源相控阵天线的散射场,将有源相控阵天线的天线模式项散射场分为天线模式反射散射场和天线模式相控散射场进行分析。最后通过一维线阵验证了理论分析结果。该分析方法和分析结果为相控阵天线RCS计算和控制提供了理论指导。The reflection coefficient of the receiver load of the feed system model for the cells in the active phased-array antenna is analyzed by S parameters. The scattering field of the active phased-array antenna is analyzed by submitting the reflection coefficient to the basic theoretical formula of the scattering fields of array antenna. The antenna model scattering of the active phased-array antenna is analyzed by dividing it into antenna model reflective scattering and antenna model phased scattering, and the analyzing results is testified by a one dimension array antenna, which plays a guidance role in the computation of the scattering fields of the phased array and its RCS control.
