W-band high-power microwave source system applied to active denial

Abstract

The invention discloses a W-band high-power microwave source system applied to active denial. The W-band high-power microwave source system comprises a frequency source, an amplifier, a power divider, a plurality of expansion interaction klystron, a power synthesizer and a directional antenna; the frequency source generates an excitation signal, the excitation signal is amplified by the amplifier and then distributed to the plurality of expansion interaction klystron through the power divider to be amplified respectively, and after being amplified by the plurality of expansion interaction klystron respectively, the processed signal is output to the directional antenna through the power synthesizer to radiate outwards and the like. The problems that a traditional gyrotron needs high magnetic field intensity, microwave output needs to be prepared for a long time, and the size is large are solved. The microwave output power and the energy conversion efficiency are improved; by adopting radial waveguide power synthesis, the power synthesis efficiency and the phase consistency are improved, and the index requirements of an active denial system on high power, high efficiency, quick response and small size of transmitted signals can be met.

Description

technical field [0001] The present invention relates to the field of microwave sources for microwave active rejection systems, and more specifically, relates to a W-band high-power microwave source system applied to active rejection. Background technique [0002] Microwave active denial belongs to a deterrent non-lethal weapon. This weapon uses the heat-sensitive effect of electromagnetic waves and uses a directional antenna to irradiate electromagnetic waves to the human skin, causing unbearable heat pain and terminating hostilities. [0003] As an integral part of the active denial system, the high-power microwave source is used to convert the DC power provided by the external secondary power supply into high-frequency electromagnetic waves. The output power of electromagnetic waves plays a decisive role in the operating distance of the active denial system. At the same time, the conversion efficiency of electric energy and electromagnetic wave energy will determine the st...
