Problems solved by technology

Its advantages are intuitive and convenient, and quick operation, but the accuracy of visual inspection varies from person to person, lack of quantitative measurement, and the reliability of measurement data is poor
[0010] The above two methods have their own advantages and disadvantages. Therefore, it is of practical significance to find a convenient and quick aiming method that can provide intuitive quantitative and high precision for measuring the aiming of waveguide antennas in the microwave radiation field.

Embodiment Construction

[0052] The present invention will be further described in detail below by taking the aiming of a rectangular waveguide horn antenna as an example in conjunction with the accompanying drawings and specific implementation methods.

[0053] Figure 1a and Figure 1b It is a composition diagram of the rapid aiming device of the waveguide antenna of the present invention. The device includes an aiming base 1, an angle indicating device 2, a laser pointer 3 and an optical sight 4, and the laser pointer 3 and the optical sight 4 together constitute an aiming point indicating device.

[0054] Among them, the bottom of the aiming base 1 realizes the fast connection with the waveguide antenna by setting a card slot 13 that is closely matched with the outer wall of the waveguide antenna (such as a rectangular waveguide); the aiming base 1 adopts the design of the same shape as the reference physical plane of the aiming axis , to conveniently realize the fast mating connection with the r...

Abstract

The invention discloses a rapid sighting device and method for a waveguide antenna. The device comprises a sighting base, an angle indication unit and a sighting point indication unit. The sighting base is of an inverted-T-shaped structure and comprises a base and a mounting shaft connected with the base vertically. The upper surface of the base is a plane, a snapping groove is formed in the lower surface of the base, and the snapping groove is in fit connection with the waveguide antenna. The angle indication unit is fixed on the upper surface of the base, and the sighting point indication unit comprises a laser indicator and an optical sighting telescope. The laser indicator is arranged at the upper end of the mounting shaft, the optical sighting telescope is arranged above the laser indicator, an optical axis adjusting unit is arranged on the laser indicator, and an optical axis adjusting unit is arranged on the optical axis adjusting unit. By means of the device and the method, rapid sighting of visual sighting points at different distances can be achieved on the premise that the waveguide antenna sighting accuracy in microwave radiation field measurement is guaranteed, and convenience of sighting of the waveguide antenna in microwave radiation field measurement can be improved.

Description

technical field [0001] The invention relates to the technical field of microwave radiation field measurement, in particular to a fast aiming device for a waveguide antenna and a method thereof. Background technique [0002] Waveguide antennas (such as open waveguide and horn antennas, etc.) are antennas with directional radiation. They have the characteristics of simple structure, moderate gain, and the coincidence of the radiation axis and the physical axis. They are commonly used microwave transmitting and receiving antennas. In the microwave radiation field measurement, the aiming accuracy of the waveguide antenna has a great influence on the measurement results and measurement uncertainty. [0003] In the radiation field measurement, the aiming of the waveguide antenna mainly includes two aspects: [0004] (1) The polarization relationship between the receiving antenna and the transmitting antenna; [0005] (2) The angular relationship between the receiving antenna and...
