A fast aiming device and method for a waveguide antenna

Abstract

The invention discloses a fast aiming device for a waveguide antenna, which includes an aiming base, an angle indicating device and an aiming point indicating device. The aiming base is an inverted T-shaped structure, which includes a base and an installation shaft vertically connected to the base. The surface is flat, and the lower surface of the base is recessed with a card slot, which is connected with the waveguide antenna; the angle indicating device is fixed on the upper surface of the base; the aiming point indicating device includes a laser pointer and an optical sight; the laser pointer is set on the installation shaft On the upper end, the optical sight is arranged directly above the laser pointer, the laser pointer is provided with an optical axis adjustment device, and the optical sight is provided with a visual axis adjustment device. The invention can realize fast aiming of visible aiming points at different distances on the premise of ensuring the aiming accuracy of the waveguide antenna in the measurement of the microwave radiation field, and improve the convenience of aiming the waveguide antenna in the measurement of the radiation field.

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 waveguides and horn antennas) are directional radiation antennas. They have the characteristics of simple structure, moderate gain, and the main axis of radiation coincides with 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 the trans...

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.
