Abstract

High precision measurement technology has a wide range of applications in industrial engineering, such as solid and liquid level measurement, detection of small defects on highly smooth metal surfaces, etc. But, accuracy of traditional measurement technology is difficult to reach the millimeter level. Based on the introduction of basic principle of FMCW radar, this paper analyzes the key technologies of high-precision radar ranging system. Related works are studied, which focuses on millimeter wave antenna, integrated circuit, and digital signal processing algorithm. At last, the future directions and outlook are prospected.
高精度毫米波雷达测距系统关键技术研究
高精度测量技术在工业工程中有着广泛的应用,如固体和液体的液位测量,高度光滑的金属表面小缺陷的检测等。但是,传统测量技术的精度难以达到毫米级。在介绍FMCW雷达基本原理的基础上,分析了高精度雷达测距系统的关键技术。对相关工作进行了研究,重点研究了毫米波天线、集成电路和数字信号处理算法。最后,对未来的研究方向和展望进行了展望。
