【摘要】 介绍了当前高功率微波(high power microwave,HPM)能量合成和功率合成的研究进展,并思考了下一步可能的发展方向。能量合成的关键在于HPM合成器,基于过模圆波导TM01模式滤波器的HPM合成器,能实现两路微波信号的同极化通道合路,并有效提高合成器的功率容量;在此基础上形成的滤波器及合成器网络,能够实现HPM多波段、多频率工作,或产生拍波。功率合成的关键在于对单个HPM微波源的频率和相位的控制。基于小信号相位牵引的新方法,实现了GW量级的HPM相位控制,注入功率比接近-43dB;同时,结合强流电子束加速器的同步控制、大功率固态注入源及相控阵天线等关键技术的发展,这些研究可为HPM源空间功率合成技术奠定基础。更多还原

【Abstract】 In this paper we present the recent progress of the HPM combination technology and the research highlights for the future.An X-band diplexer based on overmoded circular waveguides for HPM energy combination is reported.Based on the network of filters and multidiplexers,HPM pulses can be combined in arbitrary way.The frequency and phase locking is the key issue for the power combining.The initial-phase induced synchronization method is proposed and the phase control of the RBWO with power at GW level is demonstrated with injecting microwave power of 105 W.With the development of the synchronizing for high-current electron beam accelerators,semiconductor power devices,phased-array antenna and other key technologies,several HPM devices can be combined and ultra high-power pulsed electromagnetic radiation can be obtained.更多还原
