基于微波雷达的位移/距离测量技术

Radar-Based displacement / distance measuring techniques

微波雷达在民用领域是一种重要的距离测量技术,几十年来一直是国内外研究的热点。根据微波雷达的测距原理,微波雷达可分为干涉雷达、脉冲超宽带雷达、调频连续波雷达、步进频率连续波雷达,详细阐述了它们各自的距离/位移测量原理,分析了各自的适用领域及其优缺点,系统地总结了微波雷达测距技术的研究发展状况,讨论了其在未来位移测量领域的应用前景。

As one key technique for distance sensing, microwave radar has been the research highlight for several decades. This paper summarizes the development and application of microwave radar ranging systems. According to the measuring principles, the ranging systems are divided into four groups： interofermetry radar, impulse radio ultra-wideband radar, linear frequency modulation continuous wave radar and stepped frequency continuous wave radar. The measuring principles of these radar systems are presented in detail as well as the application of each system. Finally, the application prospect of radar sensing technique is discussed.
