摘要
通过研究具有单脉冲跟踪能力的单槽深波纹喇叭,并分析单槽深波纹喇叭内的差模临界截止点和电压波腹点,提出了在单槽深波纹喇叭内耦合出差模信号的思路。设计了具有X频段单脉冲跟踪能力的X/Ka双频段单槽深波纹喇叭,通过理论计算与仿真,该波纹喇叭具有良好匹配性,且辐射方向图对称,耦合出的X频段差模信号实现了单脉冲跟踪功能,验证了设计方法的有效性。
The dual-band single-slot monopulse tracking corrugated horn is studied in the paper.The cutoff frequency and voltage maximum position of differential mode is analyzed.Based upon these researches,the design strategy for coupling differential mode signal from the single-slot corrugated horn is presented. An X/Ka-band single-slot corrugated horn with X-band monopulse tracking ability is designed. It is demonstrated by the theory analysis and simulation results that in X/Ka-band the horn has excellent matching perform-ance and its radiation pattern is symmetric.Besides,the X-band differential signal coupled from the corrugated horn is able to fulfill the monopulse tracking task. It is indicated that the corrugated horn antenna satisfies all the requirements. The validity of the presented design methodology is proved.
