Millimeter Wave Radar for FOD Detection on Airport Runway Based on SAR Principle

机场跑道异物(FOD)检测对于保障飞机起降时的飞行安全具有重要意义,而国内外现有的FOD检测系统成本太高或技术不成熟,对微弱目标检测能力不够。本文采用条带扫描式FMCW雷达,引入SAR思想对信号进行相参积累处理,提高对微弱目标检测能力。论文从基本原理上阐述FMCW SAR应用在FOD检测上的可行性。最后进行了matlab仿真,验证了本文所提方法的实用性和有效性。

The detection of foreign bodies(FOD) on airport runways is of great importance to ensure the safety of aircraft during take-off and landing, however, the existing FOD detection systems at home and abroad are too expensive or immature, and the detection ability of dim targets is not enough. In this paper, a strip scan FMCW radar is introduced and SAR is used to process coherent signals to improve the detection ability of weak targets, and expounds the feasibility of FMCW SAR application in FOD detection from the basic principle. Finally, matlab simulation is carried out to verify the practicability and effectiveness of the proposed method.
