It includes several files corresponding to eight different measurement planes, where the distances between the plane containing the antennas and the plane containing the targets are 74.3913 cm, 66.4120 cm, 61.4173 cm, 56.4063 cm, 51.4131 cm, 46.3873 cm, 41.4244 cm, and 36.4289 cm. The measurement setup corresponds to a multistatic L-shaped configuration. Two open-ended waveguides were used as antennas, which were moved along the two sides of the L using two high-precision rails to transmit (Tx) and receive (Rx) signals from different positions in the acquisition array. For each Tx-Rx channel, a total of 201 equally spaced measurements of the S21 parameter were taken between 55 GHz and 60 GHz using a PNA-X device. In addition to the measurements with the metallic targets, the dataset includes two measurements with aluminum foil covering the support structure and two background measurements conducted using the same structure but without the targets. These background measurements in planes one and eight can be used to eliminate clutter caused by various environmental reflections.

Date of data collection: 04/08/2024 - 04/22/2024 Person to contact with questions: Alejandro del Hoyo Vijande (hoyoalejandro@uniovi.es) Data entry: 05/29/2025 Software (including version #) used to prepare data set: MATLAB R2023a Data processing that was performed: In addition to the files containing the scattered field measurements, a PDF file with the schematic of the measurement setup is included, as well as a sample code written in MATLAB. This code applies SAR processing based on the measurements from one of the planes and aims to demonstrate how to import one of the files and process the data to generate a reflectivity image of the region of interest. Variables The dataset consists of S21 paramenter measurements (complex values), captured with a VNA in the frequency range 55 GHz - 60 GHz. The measurements are saved in ".mat" binary files, which can be imported from MATLAB (and also other languages) and saved as a variable, as shown in the example code. File Overview This contribution consists of 14 different files. Files named "targets_planeX.mat" contain the scattered field measurements in the different planes, saved as S21 parameter values. "background_plane1.mat" and "background_plane8.mat" contain a background measurement in which the targets were removed. These measurements can later be used to remove unwanted reflections from the environment. "aluminum_foil_plane1.mat" and "aluminum_foil_plane8.mat" contain measurements of the targets covered with aluminum foil. The aim of these two experiments is to properly locate the targets along the depth (z) axis (proper focusing of the image), since the reflective surface is larger. Finally, "setup_schematic.pdf" shows the details of the measurement setup that was used, and "SAR_imaging_example.m" is a MATLAB code with an example that shows how the measurements can be processed to generate the SAR images.
