Abstract

Portable, low-cost, microwave radars have attracted researchers' attention for being an alternative noncontact solution for structural condition monitoring. In addition, by leveraging their capability of providing the target velocity information, the radar-based remote monitoring of complex rotating structures can also be accomplished. Modern radar systems are compact, able to be easily integrated in sensor networks, and can deliver high accuracy measurements. This paper reviews the recent technical advances in low-cost Doppler radar systems for phase-demodulated displacement measurements and time-Doppler analysis for structural health information, including digital signal processing and emerging applications related to radar sensor networks.

摘要

便携式、低成本的微波雷达作为一种替代的非接触式结构状态监测解决方案，引起了研究人员的关注。此外，利用其提供目标速度信息的能力，还可以实现复杂旋转结构的基于雷达的远程监测。现代雷达系统体积小巧，能够轻松集成到传感器网络中，并能提供高精度的测量。本文回顾了低成本多普勒雷达系统在相位解调位移测量和时间多普勒分析方面的最新技术进展，用于结构健康信息，包括数字信号处理以及与雷达传感器网络相关的新兴应用。
