同轴磁控管正迅速地取代用于机载搜索雷达、炮瞄雷达、测绘雷达、多模雷达、气象雷达、空中交通管制雷达和导弹终端制导系统的普通磁控管。这种趋势基本上普遍适用于新系统,而且也适用于许多现存雷达。这是由于同轴磁控管兼有简单、低成本以及新的频率捷变能力。同轴磁控管一个最重要的用途是采用颤抖调谐来改进闪烁现象、回波起伏和地物干扰的问题。本文叙述一种被称为环调谐器的新的改 Coaxial magnetrons are rapidly replacing common magnetrons for airborne search radars, gun sighting radars, mapping radars, multi-mode radars, weather radars, air traffic control radars and missile terminal guidance systems. This trend is basically universal for new systems and also applies to many existing radars. This is due to the simpler, lower cost, and new frequency agility of coaxial magnetrons. One of the most important uses of coaxial magnetrons is the use of tremolo tuning to improve the problem of flickering, echoes and terrain artifacts. This article describes a new type of ring tuner
