Space-based platform electron beam emission angle compression system based on microwave resonant cavity

The invention discloses a space-based platform electron beam emission angle compression system based on a microwave resonant cavity, which is characterized by comprising a microwave source, a circulator, a coupling waveguide and the microwave resonant cavity, the microwave source is used for generating microwaves with preset power and frequency; microwaves enter the coupling waveguide after passing through the circulator, and are coupled to the microwave resonant cavity through the coupling waveguide to generate a TM01 mode standing wave electromagnetic field; the electron beam is injected into the microwave resonant cavity along the central axis of the microwave resonant cavity, the emission angle of the electron beam is compressed under the action of the radial force generated by the TM01 mode standing wave electromagnetic field, and the compressed electron beam is output. The space-based platform electron beam emission angle compression system based on the microwave resonant cavity can be used for scenes w
