摘要
恶劣工况中的高精度液位测量是工业过程检测的难点之一,雷达测距系统由于精度高和抗干扰性强,成为国内外研究的热点。文章设计了一套基于FPGA线性调频雷达液位测量的后端数据采集和预处理软硬件系统,并研究了差频液位信号处理算法,整体系统设计具有信号处理灵活、运算能力强、可靠性高等特点。
High accuracy liquid level measurement in harsh condition is one of difficulties in the industrial process detection. Due to high precision and strong resistance to interference, radar ranging system has become a hotspot re- search of domestic and foreign research institution. In the paper, a set of linear frequency modulated radar liquid level data acquisition and pre-processing hardware and software systems based on FPGA is designed, and the associated signal processing algorithms are researched. The whole system design has many characteristics, such as flexible signal process- ing, strong operation ability, high reliability and so on.
