- X频段X band
- 举例来说,把弹头置入尖锐锥状的重返大气载具内,并于载具的外表涂布吸收雷达波的材料,就可大幅降低弹头在X频段雷达上的迹讯。For example, putting the warhead in a reentry vehicle shaped like a sharply pointed cone and coated with radar-absorbing material could significantly shrink the object's appearance on X-band radar.
- 提出了一种用于射电望远镜50m天线、S/X双频共用且对S、X双频段具有不同照射角的同轴馈源设计方法,S、X两个频段的相对工作频带宽度均为20%,S频段为同轴馈源,内导体为圆波导馈源工作在X频段。This paper presents a design method of coaxial feed that is common in S/X band,has different illumination angle of -10 dB in S and X band and can be used to illuminate a radio telescope antenna with a diameter of 50 m. The relative operation bandwidth of S and X bands is 20%25.
