EIGOR Data

The EIGOR Data Files

The microwave tomography data found here is provided with the understanding that it will be used for research purposes by the research community. If you use any of this data for results in your future publications we would appreciate it if you reference our publications wherein this data and MWT system are described. These papers can be found in the References Section of this web site. For the actual data, there is a conference presentation where we announced the availibility of this data and we have submitted a detailed description to the Inverse Problems journal. In particular, for the data description, please refer to:

For tomographic dataset #1, listed in Table 1, the general format is in 7 columns. In order, these describe the frequency of operation (in GHz), the transmitter number (1-24), the receiver number (1-24), two columns of zeros, real part of Sab for the transmit/receive pair, and imaginary part of Sab. The two columns of zeros may be ignored: these columns are intended to record the elevation and angle of a positioning motor [15], which was not used for these data. For the lossy target tomographic dataset #2, listed in Table 2, the general format is in 5 columns. The order is the same as the previous tomographic dataset, but with the two columns of zeros removed. For the radar dataset, listed in Table 3, the general data format is in 4 columns: frequency (in GHz), antenna number (x), real part of Sxx and imaginary part of Sxx.
