摘要

详细分析了天线增益下降、旁瓣信号泄露、前后比不达标、覆盖异常等常见的天线问题，通过研究信号传播理论以及小区覆盖模型，提出了一种基于天线水平波瓣区间化成形分析的故障天线定位算法，把天线水平辐射波瓣按照不同方向角度区间进行划分，分别是±[0

15°]、[16°

30°]、[31°

60°]、[61°

90°]、[91°

120°]、[121°

150°]、[151°

180°]共7个区间，通过不同区间的路测数据（如Rxqual、Rxlev Average、过覆盖指数、绝对通信距离）进行多维度关联分析，定位故障以及天线覆盖异常点。

Abstract

The problems such as decrease of antenna gain

the leakage of side-lobe signal

and the degradation of front-to-back ratio

were mainly discussed

and an algorithm of faulty antenna location based on interval analysis of horizontal beam-width was proposed

by dividing the horizontal beam-width with different radiation angle:±[0

15°]

[16°

30°]

[31°

60°]

[61°

90°]

[91°

120°]

[121°

150°]

[151°

180°].At last

through relational analysis of Rxqual

Rxlev

over-coverage index

and communication distance in different radiation angle interval

the location of faulty antenna was realized.
