Multi-mode radiation ultra-high power microwave water load

Abstract

The invention discloses a multi-mode radiation ultra-high-power microwave water load, comprising a horizontally arranged cylindrical water tank, an isolation tube coaxially arranged inside the cylindrical water tank, a gap radiation type opening waveguide coaxially installed in the isolation tube, a cylindrical water tank, a gap radiation Both the open waveguide and the isolation tube are sealed and connected, and the front end of the slit radiation type opening waveguide protrudes from the isolation tube; the inner wall of the rear end of the cylindrical water tank is located on the central axis and is provided with a reflector facing the rear end of the isolation tube. The reflection plate is used to reflect the incoming wave signal of the slit radiating open waveguide to the cylindrical water tank, and the rear end of the cylindrical water tank is also provided with a water inlet and a water outlet respectively; by opening a slit in the transmission line of the waveguide, the slit radiates microwave energy , and then add a medium-sealed gap radiator to absorb the microwave power with water and dissipate the heat through the water cooling cycle, which solves the traditional problems of poor water load matching performance, low power withstand, and large reflection coefficient.

Description

【Technical field】 [0001] The invention belongs to the technical field of waveguide feeders, in particular to multi-mode radiation high-power microwave water loads. 【Background technique】 [0002] In modern radar antenna equipment, the carrier of the link signal is mainly realized by the waveguide feeder, among which the waveguide load is widely used as the terminal equipment of the feeder link. Traditional high-power waveguide loads mainly include dry loads, dry-type water-cooled loads, and water loads, which are large in size and weight, and have no advantages in heat dissipation. High-power waveguide water loads use water as the absorption medium for microwave and millimeter wave energy. At the same time, it is also a heat dissipation medium, so it is widely used in the terminal of high-power links as a high-power load with good heat dissipation, light weight, and super-large power capacity in microwave high-power absorption loads. The traditional water load is to introdu...
