The University of Manitoba Microwave Imaging Repository: A Two-Dimensional Microwave Scattering Database for Testing Inversion and Calibration Algorithms [Measurements Corner]

We present a repository of multi-static, near-field microwave scattering measurements. The data are presented both raw (uncalibrated), and calibrated with a scattered-field calibration. Measurements were taken with 24 co-resident Vivaldi antennas in a single plane, inside an air-filled microwave tomography system. The antennas were linearly polarized in the vertical direction, and we intended for the two-dimensional transverse magnetic (scalar) approximation to apply. Data are presented for seven targets, both metallic and dielectric, with varying geometrical complexity. Data from simple geometric targets, useful for calibration using analytic equations, are given. The repository is available from the Web site: http://www.ece.umanitoba.ca/lovetri/EMILab/index.html.
