Millimeter-wave imaging of foreign object debris (FOD) based on two-dimensional approach

Description

In this paper, we present the results of image reconstructions of foreign object debris (FOD) based on 2D algorithms in the W-band (75-110 GHz). To test the feasibility of using 2D reconstruction algorithms, we first studied the relevance of two-dimensional assumption in the working frequency band for different typical debris. Thanks to the short wavelength (2.7 to 4 mm), most debris can be considered as two-dimensional. The reconstruction of complex permittivity profile for dielectric (lossy or lossless) and perfectly conducting targets is carried out using 2D-TM and 2D-TE algorithms using characteristic elements (VV, VH, HV and HH) of the scattering matrix with polarimetric measurements in multistatic configuration.
