基于单片机的天线测试参数数据采集与处理系统研究

Data extraction and processing system of antenna test parameter based on single chip

天线是无线通讯系统中发射和接收电磁波重要的前端器件。本文在分析天线方向图测试原理的基础上,介绍了一种天线测试参数的信号采集和数据处理的系统。该系统以单片机MSP430为核心,由控制模块、数据采集模块和上位机通信模块是三部分组成,通过实际测量对计算结果进行验证,得出最接近理论预期的天线方向图。该系统具有硬件造价低,测量简便,测量精度较高的优点。

In the wireless communication system,the Antenna is an important front-end device to transmit and receive the waves.Based on the principle of antenna pattern automatic measurement,the paper introduces a single extraction and data processing system of antenna test parameter.The system take MSP430 MCU as core,consist of control module, data extraction module and upper computer communication module.It is concluded that the most close to the theory of antenna pattern through actual measurement.The system has the quality of low-cost hardware,easily measure and high precision testing.
