The invention discloses a novel magnetron injection locking system based on filament injection. The novel magnetron injection locking system comprises an excitation cavity, a magnetron and a load, the magnetron is arranged on the excitation cavity and communicated with the excitation cavity, and the excitation cavity is detachably connected with the load; an antenna communicated with the outside is arranged on the magnetron; an antenna communicated with the outside couples an external injection signal into the magnetron to realize injection locking; a signal is injected from the monopole antenna and enters the magnetron cavity through magnetron filament coupling via the monopole antenna, and a magnetron output signal is output via the waveguide excitation cavity and is finally absorbed by the load via the directional coupler; therefore, the magnetron output signal can be locked by the signal injected from the external signal input position, and the frequency completely follows within the locking bandwidth. 本发
