Relativistic magnetron for realizing frequency hopping operation by utilizing transparent negative electrode

Abstract

The invention discloses a relativistic magnetron for realizing a frequency hopping operation by utilizing a transparent negative electrode, and belongs to the technical field of electronic countermeasure. The relativistic magnetron comprises a shell, a co-cavity structured positive electrode, a magnetron resonant cavity, the transparent negative electrode consisting of a plurality of sector negative electrodes, a tuning unit and an energy coupling output apparatus. According to the relativistic magnetron, the conventional columnar negative electrode is designed into the sector transparent negative electrode; the mode conversion between a pi mode and a 2pi mode is realized by changing the relative angle between the negative electrode fan-shaped emitting surface and the fan-shaped resonant cavity; when the relative angle between the negative electrode emitting surface and the fan-shaped resonant cavity is changed, the static electric field distribution between the negative electrode and the positive electrode is changed accordingly; meanwhile, the initial phase position of an electron beam relative to a resonant mode high frequency field is affected as well; therefore, when the negative electrode is rotates, the working mode of the relativistic magnetron is changed along with the change of the relative angle between the negative electrode emitting surface and the fan-shaped resonant cavity so as to fulfill the purpose of changing the frequency agility.
