摘　　要：为了进一步降低固态有源相控阵雷达天线成本,提出了一种新型的减少有源单元数的方法——相控阵天线多阶混合馈电方法,描述了在有限T/R组件数量和品种的情况下,实现相控阵天线低副瓣的技术原理和仿真实例。仿真实例表明,在有源单元数相同的情况下,采用该方法其技术指标明显优于比密度加权法,且参数调节更具有灵活性,有效地降低了相控阵雷达天线的成本。In order to reduce the solid-state active array radar antenna cost, this paper proposes a novel method of reducing active elements number-phased array multi-step mixed feed method which describes phase array antenna low side lobe technique theory and simulation examples, in the case of finite T/R number and variety. Simulation examples indicate that the multi-step mixed feed method shows more lower side lobe or larger directivity in the case of the same T/R number, and it is more flexible for adjusting parameter in comparison with the density weighed method. Moreover this method can mostly reduce the radar cost.
