Methodology for data collection: 
The field was sampled in 11 planes located at different distances from the plane containing the objects under test. In each of the planes, the scattered field was sampled forming a grid of 101x101 points, for a total of 10201 measurements along a square of 50 cm per side.

Software (including version #) used to prepare data set: 
MATLAB R2023a


Data processing that was performed: 
The scattered field measurements were processed using the Delay-and-Sum (DAS) Synthetic Aperture Radar (SAR) algorithm considering a monostatic configuration.


Variables
The dataset consists of S21 paramenter measurements (complex values), captured with a VNA at a frequency of 25 GHz. 


File Overview
The present contribution consists of two files. The first one (measurements_25GHz_11planes.mat) contains a series of measurements of the scattered electric field using two two-dimensional objects made of aluminum foil as targets. The second file (measurement_data_representation.m) is a Matlab program that imports the measurements and graphically represents the magnitude and phase of the scattered field in each plane, together with the resulting SAR image.
