| 摘 要： | 依据数值模拟结果研制了一套X波段多模微波喇叭,采用3次变张角喇叭结构,设计要求辐射功率大于3 GW,E面和H面方向图在10 dB范围内等化度良好,10 dB波束宽度为40°。近场冷测结果表明,H面10 dB波束宽度为43°,E面10 dB波束宽度为40°。远场热测结果表明,H面10 dB波束宽度为40°,E面10 dB波束宽度为41°,在初步测试中,通过对比在线测量结果和辐射场测量结果,证明研制的喇叭输出功率达1.3 GW时不会出现击穿现象。

| Abstract: | An X-band multimode conical horn has been designed with three sections of varied flare angles. The results obtained by experiment measurements are in good agreement with the simulation results. E and H patterns of the conical horn are well equal in the 10 dB regime. The simulation results show that the 10 dB widths of E and H patterns are about 40°. The high power microwave(HPM) experiment results show that the 10 dB width of E pattern is 40°, and the 10 dB width of H pattern is 43°.The conical horn's power capacity reaches 3 GW in the simulation. In HPM experiment, when the power reaches 1.3 GW,no breakdown phenomena appear. |
