| 摘 要： | 单脉冲跟踪以其精度高、速度快等优点而被广泛应用于跟踪中、低轨卫星通信天线中.本文工作研究单槽深波纹喇叭的差模临界截止点和电压波腹点，通过提取波纹槽差模信号，设计了具备L频段单脉冲跟踪能力的L/S双频共用喇叭天线.实际测试结果表明，在L/S频段该喇叭具有良好阻抗匹配特性和辐射方向图旋转对称特性，且L频段差模信号实现了单脉冲跟踪能力，该喇叭天线电气性能满足工程应用要求.

| Abstract: | Monopulse tracking is widely used in tracking middle or low orbit satellite communication antenna.The cutoff frequency and the voltage maximum position of the differential mode of the single-slot corrugated horn is studied.Based on the differential mode signal, an L/S dual-band corrugated horn with monopulse tracking ability in L-band is designed.The measured results demonstrate that the horn has good matching performance and symmetric radiation pattern in L/S band.Besides, the differential signal coupled from the corrugated horn is able to fulfill the monopulse tracking in L-band.It is indicated that the corrugated horn antenna satisfies the requirements in application. |
