摘　　要：在对国内外HPM源辐射场测量系统进行分析的基础上,提出了一种HPM辐射场测量系统功率分配设计;基于X波段大功率微波源,对BJ-100高方向性定耦、SMA微波电缆和SMA同轴衰减器在相应功率水平下开展了功率容量实验研究,并进行了功率分配设计可行性验证;基于X波段RBWO,开展了功率分配设计在Gw级功率测量中的应用研究。实验结果表明,BJ-100高方向性定耦、SMA微波电缆和SMA同轴衰减器分别在300 kW,1 kW,400 W工作正常,验证了HPM辐射场测量系统功率分配设计的合理性与可行性。A power division design was proposed based on the analysis of a high power micro- wave measurement system in radiation field. BJ-100 directional couplers, SMA coaxial cables, and SMA coaxial attenuators were tested with an X-band klystron and an X-band magnetron at the power proposed in the power division design to verify the division design. The design was used in the power measurement of an X-band relativistic back wave oscilla- tor, and the results show that the BJ-100 directional couplers, SMA coaxial cables and SMA coaxial attenuators work well at the power of 300 kW, 1 kW and 400 W, respectively, indicating the feasibility of the division design.
