Description
Technical Field
The invention belongs to the field of computer software and communication technology composition, and particularly relates to a directional diagram data processing system, a directional diagram data processing method and a storage medium thereof.
Background
Conventional base station antennas contain several ports, each operating in a single frequency band, with one beam per port. When the antenna is measured and data are processed, the performance of each port can be obtained only by testing and analyzing the ports one by one, so that the performance of the whole antenna can be obtained.
With the development of mobile communication technology, after 5G is widely used commercially, the coexistence of 2G, 3G, 4G and 5G networks will be maintained for a long time. In order to save the space of the sky, it is an obvious trend to provide an electrically tunable base station antenna with multiple ports, multiple beams and multiple frequency bands shared by multiple systems to replace the traditional single-frequency-band and single-standard antenna. The multi-port, multi-beam and multi-band base station antenna has one antenna with more than ten ports and a plurality of sub-arrays, each sub-array has one to a plurality of beams, frequency bands and frequency bands are crossed, and the performance of the antenna has no simple inclusion relation with the ports, the frequency bands and the frequencies.
In order to scientifically evaluate the performance indexes of the base station antenna, the international organization "next generation mobile network Alliance (NGMN Alliance)" proposes a BASTA evaluation specification for evaluating the compliance of each index of the antenna by a statistical method, and evaluates each index of antenna radiation beam such as gain, beam width, tilt angle error, front-to-back ratio, side lobe suppression, cross polarization rate, and the like, generally requires measuring each integral downtilt angle and a plurality of frequencies of each port, screening a directional diagram according to various conditions such as subarray, port, frequency band, tilt angle, and the like, extracting the antenna index, and performing statistical analysis. The traditional method is that directional pattern analysis software extracts measured indexes of each port one by one, directional pattern indexes of required frequency and inclination angle are manually extracted, and document tools such as EXCEL are matched to evaluate the complete antenna performance. Such an analysis method is inefficient and difficult to automate.
Therefore, a system which can classify and sort the digraph data according to the port, the frequency and the inclination angle, automatically screen the data and extract indexes can effectively reduce the working intensity and reduce the manual participation.
