Abstract 

This dataset contains the measurement in an ultrawide band (UWB) system in the 6.5 GHz band, considering the presence of the human body as the only obstacle. There are measurements in line-of-sight condition to compare the results of the analysis performed. The measurements are part of our research on the adverse effects of the body shadowing in pedestrian localization systems. The measurements were obtained in three distinct scenarios.

The UWB system has four fixed terminals and one mobile terminal. The mobile terminal is worn on the chest of the person.

 A script is provided for loading the dataset. It is recommended to use Matlab 2022 version for its execution.

Instructions: 

The device was worn on the chest.

The WithBody files contain the measurements with the human body presence.

The WithoutBody files correspond to the measurements without the presence of the human body.

The structure of the data is as follows:

TX RX 1/PER TX_TIMESTAMP(dw_time) RX_TIMESTAMP(dw_time) TOF(nanoseconds) DISTANCE(meters) STD MaxNoise FP AMPF1 AMPF2 AMPF3 N MaxCIR TEMP_VOL TEMPERATURE(°c) VOLTAGE(v) CIR 

To execute the .m files change the path of the lecture data, the .fig file to the correspondent ground truth.
