Problems solved by technology

[0003] With the application of the microwave unlicense frequency band, the carrier frequency band is greatly increased, the beam is narrowed, and the main lobe of the antenna is significantly reduced, which greatly reduces the range where the multimeter can detect the signal strength. It takes a long time, and the difficulty of antenna alignment for narrow beam antennas is increased compared to wide beam antennas

Embodiment Construction

[0063] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0064] The electric field intensity radiated by the antenna changes with the space, and this change trend is described as the antenna pattern, which usually has three-dimensional and two-dimensional. The two-dimensional antenna pattern includes the expressions of the horizontal antenna pattern and the vertical antenna pattern, such as figure 1 Shown is the antenna pattern in the vertical direction. Depend on figure 1 It can be seen that there are many lobes in the...

Abstract

An embodiment of the invention discloses an antenna alignment method and system. Handshake information of two end antennas mutually aligned is scanned in a negative SNR (signal-noise ratio) communication manner; a curve or surface of receiving statistic changing with angle is generated according to the receiving statistic of a carrier signal; a rough scanning range is determined according to the curve or surface of the receiving statistic changing with the angle, generated according to the receiving statistic; the end antennas perform alternate rough scanning; accordingly, antenna alignment is achieved. The antenna alignment method and system has the advantages that alignment accuracy is guaranteed, alignment time is shortened, manpower cost is saved, and mass application of microwave links is facilitated.

Description

technical field [0001] The present invention relates to the communication field, in particular to an antenna alignment method and system. Background technique [0002] Antenna alignment refers to adjusting the positions of the two antennas for microwave communication so that the main lobes of the two antennas are aligned. The two antennas for microwave communication are called opposite antennas. At present, the common antenna alignment method is that technicians use a multimeter to measure the received signal strength of the antenna at different angles, and judge the main lobe direction of the antenna based on these data, and then manually adjust the antenna to the main lobe direction. [0003] With the application of the microwave unlicense frequency band, the carrier frequency band is greatly increased, the beam is narrowed, and the main lobe of the antenna is significantly reduced, which greatly reduces the range where the multimeter can detect the signal strength. It ta...
