RIFD technologies are applied in a various number of environmental monitoring applications. Efficient energy management is one of the most important prerequisites for the realization of such systems and the power consumption of the RFID tag during radio transmissions must be kept low. The proposed system is composed by the RFID tags distributed on the(More)
During the past years, the Remote Sensing Group of Polytechnic of Turin developed a prototype of a X-band mini weather radar, capable to detect and measure rain with good space and time resolution. These radar systems may suffer for some degradations due to external factors like temperature fluctuations: some adjustment should be automatically implemented(More)
The problem that we have addressed with the presented study is the absolute localization of buried RFID tags in an outdoor environment where the tag is. This is the scenario that we have envisaged when the RFID sensors are installed inside a moving body like a glacier or a slow landslide. During the tags dislocation it is possible to measure the depth of(More)
This contribution deals with the technological aspects of a research funded in the framework of a Scientific Cooperation program between Italy and Israel. The aim of this research is to evaluate if real-time estimates of precipitation at high spatial and temporal resolution can significantly improve the efficiency of agricultural management by optimizing(More)
The FWI-tel instantaneous is a system for computing a forest fire risk index; it elaborates instantaneous weather maps to evaluate fire risk indicator on alpine regions. This system is based on the previsional Canadian Fire Weather Index (FWI) adjusted for continental Europe latitudes and climatology and adapted to alpine regions orography. FWI is a(More)
Long range weather radar observations are regularly used for short term forecasting and severe weather warning systems. Here, data acquired by portable and short range X-band mini weather radar are used, in order to try to forecast storms which are moving within the radar visibility area. Key step in developing an adequate storm forecasting system is the(More)
The X-band radar installed in Turin was used to analyze extreme events. About 3 years of radar maps have been analyzed in comparisons with about 30 years of measurements made by rain gauges located in the same area. The entire monitored area was divided into 4 subareas considering the complex orography near Turin, namely the flatlands, mountains, hills and(More)
This paper describes a technique developed to understand if a radar receiver filter is tuned or not, manually detuning the receiver central frequency and statistically analyzing the power distributions of Ground Clutter echoes observed in clear sky conditions. Statistical parameters characterizing such distributions are quite sensitive to the radar receiver(More)
In this paper, the application of a weather radar software for storm identification, tracking and forecast to a short range X-band rain radar observations is presented. Preliminary results are given, applying such tool to high space-time resolution both convective and stratiform precipitation scenarios. Good qualitative and quantitative agreement are(More)
