Problems solved by technology

For high-power microwaves (especially low-frequency) whose pulse half-power width is less than 100ns, generally 0.5m 2 The power capacity of the broadside longitudinal slot waveguide slot array is less than 2GW, which severely limits the application of the broadside longitudinal slot waveguide slot array in high-power microwaves, and it is urgent to develop a broadside longitudinal slot waveguide slot array slot structure with higher power capacity

Abstract

The invention discloses a high-power broadside longitudinal slot waveguide slot array. The array comprises a waveguide and an elliptical slot; the waveguide is a broadside longitudinal-seam rectangular waveguide, and a short-circuit surface is arranged at the tail end of the waveguide in a microwave propagation direction; and the slot is distributed on one side of the waveguide in a staggered mode along the two sides of the center line of the broadside of the waveguide, the long axis of the slot is parallel to the center line of the broadside of the waveguide, and the short axis of the slot is in the direction of the broadside of the waveguide. According to the high-power broadside longitudinal slot waveguide slot array, the slot area of the waveguide slot array is larger, and the high power capacity is achieved.

Description

technical field [0001] The invention relates to a high-power wide-side longitudinal slot waveguide slot array, which belongs to the technical field of high-power microwaves. Background technique [0002] The waveguide slot array is the main technical route of the large-aperture high-power microwave antenna. The radiation slot is the radiation window of the waveguide slot array, and its function is to realize the high-gain and high-efficiency radiation of high-power microwaves. There are two types of waveguide slot arrays: traveling wave array and standing wave array. The standing wave array has the characteristics of high aperture efficiency (the aperture efficiency of the standing wave array is generally greater than 90%, while the aperture efficiency of the traveling wave array is less than 80%), and is widely used in high-power microwaves. Broadside longitudinal slot waveguide slot array is a typical standing wave array, which not only has high aperture efficiency but a...
