The ZIP file has 201 *.txt files, one *.txt file per frequency (the frequency value, in MHz, is indicated on the name of each *.txt file)Dataset 02: ZIP file containing the field scattered by the targets in the imaging domain (see the image “PictureSetup.png”). The ZIP file has 201 *.txt files, one *.txt file per frequency (the frequency value, in MHz, is indicated on the name of each *.txt file)This dataset corresponds to the measurements of a monostatic microwave imaging system, collected using the facility described in [1]. The first dataset, "Escatt_meas.mat", corresponds to the field scattered by the targets shown in the picture. Two targets were considered: a 18 cm long × 14 cm diameter metallic can, and a 18 cm diameter and 4 cm thick plastic disk, placed 22 cm above the metallic floor of the facility. The size of the scattered field acquisition domain was Lx × Ly = 65 cm × 40 cm, discretized every δx,y = 10 mm (λ/2 at the center frequency of 15 GHz), and placed 1 m above the floor of the measurement facility. The Tx and Rx antennas were two Standard Gain Horn (SGH) horn antennas [2]. The second dataset, "Erad_horn.mat" is the near field radiated by the Tx and Rx Standard Gain Horn (SGH) antennas in the 12-18 GHz frequency band. The field radiated by these antennas was measured in the same 12-18 GHz frequency band, in an acquisition domain discretized also every 10 mm, placed 50 cm above the SGH aperture. The field radiated by the SGH was processed using the backward transformation algorithm described in [3] to obtain the SGH aperture fields This dataset can be processed following the methodology described in [4],[5] (modified Delay-and-Sum algorithm) and in [6] (modified Fourier-based imaging algorithm).
