MORENO, David; VELOZ, Nancy; MORENO, Hugo  and  SANTACRUZ, Fabricio. Risk level measurement system for landslide zones using SDRadar technology in lab environment. Maskay [online]. 2020, vol.10, n.1, pp.1-7. ISSN 1390-6712.  https://doi.org/10.24133/maskay.v10i1.1245.

This prototype was carried out in lab environment at ESPOCH in Ecuador, using USRP B210 working at 5GHz and including two ZJL6G+ amplifiers in cascade connection with 20dB of total gain, in order to improve the overall system power. In the measurement stage, three different samples with different humidity levels were used to determine the risk in diverse conditions. The sample materials were macadam, soil and sand. Depending on their humidity level, risks oscillate between maximum and minimum, where high humidity led to a high risk and inversely. Macadam was the best material for a landslide area since it showed lowest permittivity indexes, in consequence lowest risk. Results were processed in order to get reflection and relative permittivity values and afterwards they were stored in a database to be analyzed and determine levels of risks simulating landslides as function of humidity level.

Keywords : SDRadar; USRPB210; landslide zones; risk level.
