Abstract
During the integration of High Power Microwave(HPM)systems,the docking condition of the microwave source and the transmission-emission subsystem affects the HPM system performance directly.Poor docking conditions may cause radio frequency breakdown at the connection surface,which will result in the reduction of the entire system's output power.Therefore,diagnosing the docking state of the system is of great engineering significance.For this reason,a non-contact high-power microwave transmission technology is investigated in this paper,and an injection power measurement method is proposed for a Ku-band GW-level HPM system using a conical horn as the feed source.Based on simulation designs,key subassembly of the technology was developed.In addition,the small signal test and power handling capacity assessment of the subassembly were carried out.The experimental outcomes demonstrated that the reflection coefficient was consistently below-26 dB,the coupling coefficient was(-0.31±0.07)dB within the frequency band of(15±0.15)GHz,and the power handling capacity exceeded 900 MW.The experimental and simulation results show that the proposed measurement technology not only has the characteristics of stable coupling coefficient and low test errors,but also can effectively measure the microwave power injected by HPM source through the feed-horn and diagnose the docking state of the HPM system.关键词
