摘　　要：射频电调滤波和射频干扰抵消一直是射频干扰抑制领域的研究热点,两项关键技术的结合被认为是一种提高接收机抗已方合作干扰能力的射频保护方案。本文系统梳理现有射频保护电路的优缺点,经过调研对射频电调滤波和射频干扰抵消的前沿技术进行归纳总结,针对频谱感知接收机抗未知非合作干扰的应用需求,初步提出基于感知主路与抵消辅路的频谱感知接收机宽带自适应射频保护架构,并对重难点问题进行了探讨。Radio frequency(RF)tunable filtering and RF interference cancellation have always been the focus of RF interference suppression research.The combination of these two key technologies is considered to be a RF protection scheme to improve anti-known cooperative interference ability for receivers.This paper systematically sorts out the merits and drawbacks of the available RF protection circuits and summarizes the advanced technologies of RF tunable filtering and RF interference cancellation after investigation.Aiming at application requirements of anti-unknown non-cooperative interference,based on the main path of RF spectrum sensing and the auxiliary path of RF interference cancellation,the architecture of wideband adaptive RF protection(WARP)for spectrum sensing receivers is preliminarily proposed,and the difficult problems are discussed lastly.
