Implementación de un sistema de medición del nivel de riesgo en zonas de deslave a través de tecnología SDRadar en la zona parroquial Nabuzo del cantón Penipe.

Abstract

A risk detection system analysis for landslide-prone areas was conducted using SDRadar technology by replicating previous models in a controlled environment for parameterization and evaluating its functionality in the landslide zones of Nabuzo Parish in Penipe canton. The study examined the factors influencing soil moisture and slope inclination variables. The tools for generation, transmission, reception, and processing of a frequency-modulated continuous-wave (FMCW) radar signal were employed using GNU Radio Companion. The information was processed in Matlab, where the relative permittivity was calculated from the reflection index. After ensuring correct functionality between hardware and software, the system was implemented using a USRP B210 board connected to a computer. Two bow-tie patch antennas with an operating frequency of 3 GHz and gains of 3 dBi were utilized for signal transmission and reception. To enhance the radar's power, two cascaded TQP3M9037 amplifiers, each providing 10 dBm, were used, resulting in a total gain of 20 dBi and significantly improving the system's power for measuring the relative permittivity of the material (black soil) with different moisture levels (minimum, slight, moderate, and strong) and two slope inclinations (steep and very steep). Four risk levels were determined (low, medium, high, and very high) based on the values. The system provides valuable information for future research; thus, it is recommended to continue monitoring by increasing the variables affecting the risk of landslides.
