Characterization of Foreign Object Debris Detection at 93.1 GHz using Metallic Cylinder Simulators

In this paper, the 3×2-cm dimension of foreign object debris (FOD) simulators is used to characterize the FOD detection. The FOD simulator used as the target is made of metal cylindrical shape. The characterization method to measure the radar cross-section (RCS) of FOD simulators at several locations is proposed. This work was conducted in a real airport runway environment at Kuala Lumpur International Airport (KLIA). Furthermore, the measurements were carried out at 93.1 GHz frequency for a Frequency Modulated Continuous Wave (FMCW) radar detection system. The backscattering characteristics of the radar target, specific design of FOD simulator, the analytical deviation and measured RCS value, and experimental procedures are presented in this paper.
