Abstract
Renewable energy sources have gained much attention due to the urge to get clean energy. Among the main options being studied, wind energy is a strong contender because of its reliability thanks to the maturity of the technology and relative cost competitiveness. In order to harvest wind energy more efficiently and to improve safety considerations, the wind turbines blades must be monitored regularly to ensure that they are in good condition. This is even truer in cold climate areas where, because of sub-zero temperatures and humid environment for larger periods of the year, icing represents a significant threat to the performance and durability of wind turbines. Therefore, a structural health monitoring (SHM) system is of primary importance. Recently, there has been a significant interest in employing high frequency radar imagery for Non-Destructive Testing (NDT) and Non-Destructive Evaluation (NDE). The main motivations for using this technology are: it allows penetration of most non-metal and non-polarized materials, it provides the ability for in-depth information, and the millimeter waves pose no health risk to the operator. The main goal of this research is to check the ability of a frequency-modulated continuous-wave (FMCW) radar in performing real-time ice detection onto a glass fibre plate when it works in the frequency band from 57-64 GHz. The technology effectiveness to achieve the aforesaid task is proved in a climatic chamber under controlled humidity and thermal conditions.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
