Longitude and latitude location method of outdoor shortwave antenna

Abstract

The invention discloses a longitude and latitude location method of an outdoor shortwave antenna, relates to the technical field of antennas and aims to solve the problems that an existing location method is long in required time and poor in flexibility. The longitude and latitude location method of the outdoor shortwave antenna includes the steps that longitude and latitude of an antenna tower are obtained and serve as a first latitude and longitude point; the first latitude and longitude point serves as a point of intersection of the equator and the prime meridian, and the longitude and latitude on the earth are reset; the longitude and latitude of a destination are converted into a second longitude and latitude point according to the reset longitude and latitude; the second longitude and latitude point and the first longitude and latitude point are connected, and the included angle between the connection line and the reset equator line serves as a first angle; the rotation angles required by the antenna tower are a second angle, a third angle, a fourth angle and a fifth angle when it is detected that the destination is located in the east direction, in the north direction, in the west direction and in the south direction respectively; the function relational expressions among the actual rotation angles of the antenna tower and the second angle, the third angle, the fourth angle, the fifth angle and the fist angle are established respectively, and the actual rotation angle of the antenna tower is determined. The longitude and latitude location method is mainly applied to shortwave antennas.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to a longitude and latitude positioning method for an outdoor short-wave antenna. Background technique [0002] At present, the domestic traditional outdoor short-wave large-scale antenna system is mainly based on the broadband curtain antenna. The broadband curtain antenna is an antenna array composed of multi-layer full-wave or half-wave dipoles. Its horizontal pattern is controlled by the number of array element antennas in each layer, and the vertical pattern is controlled by the number of layers of array element antennas and the lowest layer of antennas. Ground clearance control. Because the short-wave antenna has the advantages of wide frequency range, high power, and long propagation distance, it is widely used and is one of the important means of modern long-distance radio communication. [0003] Among them, when using the existing outdoor shortwave antenna longitude and ...
