摘　　要：提出了四喇叭单脉冲抛物面天线和多波束抛物面天线共用一个抛物面来提高四喇叭单脉冲抛物面天线的搜索性能。计算了个实例,该多波束抛物面天线的波束扫描角达22.78°、口径直径为53.33λ(λ=0.03 m)、馈源方向图为cosθ、增益比原四喇叭和波束下降4 dB左右。Improving scan performance of a mono - pulse antenna by using a multibeam antenna is presented. The 22.78° scan ease with 53.33 λ diameter aperture and a feed radiation pettern of cosθ has a 4 dB drop of peak gain.
