Detection laboratory, using drones, ground interferometer radar and digital return
The proposed laboratory uses a series of innovative methods and technologies that can detect, monitor and implement alerts in situations of imminent disaster; therefore it is aimed at improving the knowledge of the calamitous phenomena of the territory in order to increase the ability to assess and prevent the impacts and associated risks. Currently the technological innovation is undoubtedly represented by the Remote Pilot Aircraft Systems (SAPR), better known as drones, which occupy a highly important role, which is also confirmed by an increasingly promising and profitable market. The SAPRs offer multiple possibilities of use, being able to fly over inaccessible areas in real time, to be equipped with different types of sensors on board; they respect the concept of “low-cost high performance” and allow an easy and effective repeatability of the measurements for correct periodic monitoring, both locally and on a large scale.
The real innovation is represented by LiDAR sensors, real laser scanners appropriately “miniaturized” for use on drones. Given that have already been designed and marketed SAPRs exemplars that can support multiple sensors at the same time, LiDARs are often also associated with cameras for photogrammetric use or other devices, making the systems even more performing and allowing for the simultaneous recording of different data.
The use of ground-based interferometric radar technology has been envisaged to integrate these survey systems with drones and. They are particularly suitable for use in civil protection activities, for example during the management of emergencies related to hydrogeological instability or in the management of quarries and mines.
