摘要
基于MLAT多点定位的A-SMGCS系统可显著提高机场场面监视的精度。对机场场面监视雷达中数据采集系统的设计方法进行详细地阐述。利用高速A/D实时采集对数放大器输出的回波数据,经F P G A处理后,通过光纤发送至信号处理。实际工作结果表明,该设计方案成熟、可靠,为类似的系统或项目提供一个有益的借鉴。
A-SMGCS system based on MLAT can significantly improve precision of airport surface detection equipment. This paper introduces design methods of data acquisition system in airport surface surveillance radar in details. High speed A/D real-time acquires echo data of logarithmic amplifier, after processed by FPGA, the data is transmitted to signal processing system through optical fiber. The practical work results indicate that the design scheme is very mature and reliable, may be a useful reference for similar systems or projects.
