Indoor positioning technology is used in all aspects of life. We study the positioning method of a UWB radar network. Because of the interference in the indoor environment, the UWB radar measurement data produce abnormal values. In order to eliminate the outliers, the method of fitting the known true value with the actual measured value is used to obtain the linear relationship between the true value and the measured value, so as to get the unknown true value through the measured value.

In this research, we applied a ground-penetrating radar (GPR) approach for excavating the ancient archeological baptism site of the Jordan River. The GPR survey was carried out at representative locations along parallel profiles using a subsurface interface radar system. The GPR profiles revealed multiple subsurface anomalies across the study area. Many features were detected in the study area, such as a buried wall, channels and a pottery pipe at the Elijah's Hill site.

Medium-frequency radars measure winds (between 55 and 100 km altitude). As part of their final year undergraduate project, the lead author used two radars in Antarctica to look at how the wind speed varied with the aim of identifying when the wind was too fast to be a real measurement. Instead, we discovered that the variance depends strongly on factors in the analysis technique rather than on natural features such as gravity waves, and that the Sun and geomagnetic activity play a role.

The paper presents the first results of ground penetrating radar investigation in the church in Kłodzko, Poland. The research was part of SEG Field Camp, which was organized by SEG Student Chapter Cracow and SEG Bucharest Student Chapter. The aim was to verify the presence of possible underground structures. Among the most important discoveries are previously unknown crypts. Results of the research might be helpful for future archeological excavations and other investigations in the church.

Ground-penetrating radar (GPR) is a powerful tool that uses electromagnetic waves to obtain 3-dimensional images of natural or man-made structures and subsoil. It is employed in a large variety of applications in which non-destructive investigations are required. This paper deals with the use of GPR for the evaluation of moisture content in wood. The results of our work are of great interest for the preservation of timber structures, as moisture content is highly relevant to wood deterioration.
