Waveguide-slot power division network and process realizing method thereof

Abstract

The invention discloses a waveguide-slot power division network and a process realizing method of the network. A positioning block is arranged between flange plates of two ends of a slotted waveguide, and the positioning block and the flange plates are simultaneously welded with aluminum waveguide profiles through aluminum soldering. The positioning surface of the positioning block and a waveguide slot are processed by taking the end surface of the flange plate of one end as a reference, each waveguide installation positioning surface is processed according to the actually measured size of a fitting surface, and high precision can be obtained. The slot of the slotted waveguide and each inner waveguide cavity of radiating waveguides are processed through one-time clamping. A whole assembling component enters a salt-bath furnace to carry out salt-bath welding, so that the structural strength is enhanced. According to the waveguide-slot power division network and the process realizing method of the network, the purposes that radio-frequency signals are distributed through the power division network and the signals are respectively sent into each radiator are achieved; and the power division network is integrally processed and welded through parts, the strength and precision are increased, and the using requirements of a high-precision radar in various environments are favorably met.

Description

technical field [0001] The invention relates to a structural design of a waveguide crack power dividing network of a search radar, in particular to a structure and a technical realization method of the power dividing network. Background technique [0002] The existing waveguide slot power division network is generally composed of slot waveguide, radiation waveguide and sum and difference branches, and the magic T is composed of sum and difference branches and slot waveguide. In the transmitting state, when the radio frequency signal enters the power dividing network from the input port of the power dividing network, the power dividing network will send the input signal energy to the phase shifter connected to its output port according to the specific amplitude requirements, and after the The phase shift output of the phaser is sent to the last radiator. In the receiving state, the low-power radio frequency signal enters the cracked waveguide from the radiation waveguide, an...

AI Technical Summary

Problems solved by technology

[0003] Existing problems: assembly of components requires additional processing tooling, and the positioning between the center of the radiation waveguide and the center of the crack in the cracked waveguide is determined by the spacer between each single waveguide

Due to the accumulated errors in assembly and processing, the accuracy is not high; the parts are connected by glue, and the strength is difficult to meet the requirements of the actual use environment.
