Embodiment Construction
[0036] In order to better illustrate the purpose, advantages and technical ideas of the present invention, the present invention will be further described below with reference to specific embodiments. It should be noted that the specific examples given below only serve to explain the present invention in detail, and do not limit the present invention.
[0037] Figure 1 to Figure 5 This is a schematic diagram of the structure of the high-power microwave on-line measurement device of this embodiment. The on-line measurement device includes a main transmission waveguide, a coupling slot, a choke groove, a coaxial electrical probe, and a replaceable probe fixing plate.
[0038] The main transmission waveguide is a rectangular waveguide with a wide side a=72.14mm, a long side b=34.04mm, and a length X=100mm; during processing and assembly, the main transmission waveguide is divided into two parts, left and right, which are fixedly connected by a large flange. One side of the main...

Description
technical field [0001] The invention belongs to the technical field of high-power microwave measurement, in particular to a high-power microwave on-line measurement device based on a choke coupling structure. Background technique [0002] From the perspective of practical high-power microwave measurement devices, the development of high-power microwave measurement devices mainly focuses on the following aspects: (1) miniaturization and compactness of the device; (2) high power capacity; (3) low response delay; (4) Wide operating frequency band; (5) Long service life; (6) Easy installation and use. High-power microwaves have the characteristics of high power, short pulse duration, and single pulse. These characteristics determine that high-power microwaves cannot be measured by conventional microwave measurement methods. In order to meet the development needs of high-power microwave measurement, high-power microwave measurement devices with the characteristics of compact str...
