Species broad spectrum of high power microwave system based on a flat type Blumlein transmission line

The present invention discloses a kind of a broad spectrum of high power microwave system type plate Blumlein transmission line based, comprises a pulse drive source, the microwave oscillator and the antenna; nanosecond pulse is generated by means of the pulse driving source, and a microwave oscillator using nanosecond pulses modulated oscillation pulses with a specific frequency, produce a broad spectrum of high-power microwave radiation in the space through the antenna; microwave oscillator is constituted by a flat type Blumlein transmission line and a gas spark switch; the plate Blumlein transmission line can be adjusted in position on the electromagnetic pulse transmission direction ; gas spark switch is mounted in the chute between the lower plate, the gas and the relative positions of the spark switch plate by generating a given pulse oscillation frequency; using the present invention can be constructed capable of producing a center frequency of several hundred MHz ~ broadband high power microwave system specific configuration of several GHz, and for online adjustment of the center frequency; small solve technical problems of high power microwave frequency may be generated.
