High-power microwave coupling measuring apparatus

Abstract

The invention discloses a high-power microwave coupling measuring apparatus. The apparatus comprises a flange, a main waveguide, a coupling waveguide, an electric probe, an insulating support structure, a coaxial outer conductor and a radio frequency coaxial connector. The electric probe, the coaxial outer conductor and the insulating support structure form a waveguide of a coaxial structure, and the electric probe is fastened inside the coaxial outer conductor in a coaxial manner by means of the insulating support structure. The main waveguide is directly connected to a high-power microwave source microwave output pathway or a high-power microwave reception antenna through the flange. The coupling waveguide, connected to the main waveguide and the coaxial outer conductor, conducts a small amount of coupling sampling on high-power microwave signals in the main waveguide, and further feeds in the coaxial structure formed by the electric probe and the coaxial outer conductor. The radio frequency coaxial connector is connected to the coaxial outer conductor and an external coaxial cable. Through the technical scheme of the invention, the measuring apparatus is improved in power capacity and reliability.

Description

technical field [0001] The invention belongs to the technical field of high-power microwave measurement and relates to a high-power microwave coupling measurement device. Background technique [0002] Establishing a high-power microwave coupling measurement device is of great significance to high-power microwave generation technology. In recent years, with the continuous development of high-power microwave technology, the microwave power generated by high-power microwave sources has been further increased, and the pulse width has been further expanded. Because the traditional high-power microwave coupling measurement device has certain limitations in power capacity, it is difficult to directly extend it to the diagnosis of higher-energy high-power microwave pulses. In this case, it is necessary to develop a high-power microwave measurement device with higher power capacity. appears to be urgent and necessary.

Problems solved by technology

[0008] The main problems of this structure are: the number of coupling holes and hole spacing of the measurement device need to be carefully designed and processed, and processing errors may reduce the performance of the coupler. It is difficult to achieve a low coupling degree, so that the microwave field coupled into the rectangular waveguide Before outputting to the outside, it needs to be further attenuated by waveguide attenuation, and at the same time, it needs to be further converted by a wave-to-synchronous converter. These intermediate links increase the uncertainty of the measurement system
