The invention provides an antenna performance analysis method and device based on frequency sweep data. The method comprises the steps of: acquiring frequency sweep data of an antenna, determining a sampling point corresponding to each frequency sweep data and a position thereof, and distributing all the sampling points in a circular area using the position of the antenna as the circle center according to the positions of the sampling points; dividing the circular area into a plurality of sectors having predetermined central angles, and determining radiation leaves in the circular area according to the sampling points distributed in the circular area, wherein each radiation leaf is composed of one or more continuous sectors, each sector of the radiation leaf has at least one sampling point, and the sector adjacent to the radiation leaf does not have sampling points; for each radiation leaf, determining a lobe of the antenna and a corresponding radiation direction according to the signal intensity of the sampling points in the radiation leaf; and analyzing the performance of the antenna according to the frequency sweep data of each lobe of the antenna. The method and the device are simple and feasible, and have the characteristics of high efficiency and intuitiveness.
Description
technical field [0001] The invention relates to the field of wireless technology, in particular to an antenna performance analysis method and device based on frequency sweep data. Background technique [0002] With the gradual expansion of wireless networks, problems with the performance of wireless devices have gradually emerged. Especially with the increase in the density of base station construction in cities in the past two years, antenna performance issues have also begun to attract more and more attention from operators. In particular, due to the gradual aging of antenna equipment, the vibrator or feeder line technology of the centralized collection antenna is not up to standard, resulting in a serious decline in antenna gain, which greatly affects the depth of network coverage and customer perception. [0003] For this problem, the following methods are generally used to troubleshoot and optimize: [0004] 1. Use the drive test method to reversely calculate the anten...
