Estudio de un sistema de medición de niveles de riesgo para zonas de desprendimientos a través de tecnología SDRadar en un ambiente de laboratorio.

Abstract

A study of a measuring system of risk levels was developed in detachments zones using SDRadar technology at a lab environment. The first step was the simulation testing of how a radar works into the Matlab software, once its operation was understood and after several simulations, the measuring system was implemented by connecting two USRP B210 cards to a couple of computers, one for broadcasting and the other for reception of the signal, then an antenna was installed in each devise with an operation frequency of 5GHz and an amelioration of 10db. For boosting the power of the radar, two ZJL6G+ amplifiers were used in cascade of 10db each, which made an improvement of 20db in the power system. To measure three materials such as soil, sand and macadam in different moisture degrees (zero, mild 1, mild 2, mild 3, moderate 1, moderate 2, moderate 3 and strong) at the obtained permittivity values, two scenarios of detachment risk were compared, one extremely dry and the other extremely wet, determining that there is a risk in <3 and >6 values. The system provides important information for future investigations or implementations, being the one proposed in this study the most recommendable.
