摘　　要：铁氧体移相器是相控阵雷达的关键元件,采用有效的相位补偿技术,提高铁氧体移相器的移相精度,是一个重要的研究课题。依据移相器相位与铁氧体材料剩磁状态的相关性,通过分析材料内应力对材料剩磁状态的影响,针对传统移相器采用的瞬时能量反馈技术对相位补偿不足的问题,提出了逐次通量反馈技术。探讨在高功率条件下,减小材料内应力对材料剩磁状态所带来的影响,提出提高电控铁氧体移相器相位稳定性的技术途径和手段,实验结果证明了此技术的可行性。Phase shifter is the key part of phase-array radar,so enhancement of phase shifting precision using effective phase compensation method is an important research topic.Based on the relationship between the phase and remanence state of the ferrite,and through the analysis of the dependence of remanence state on the internal stress of the ferrite,a technology of successive flux feedback was proposed to solve the problem of insufficient phase compensation of common instantaneous energy feedback.Aiming at decreasing the influence of the internal stress on the remanence state in high power condition,technological mean was proposed for improving phase stability of voltage-controlled ferrite phase shifter.The design result verifies the feasibility of the technological method.
