The time required for instrument installation is about 2h.
The instrument has been specifically conceived for outdoor use and is equipped with an
installation system designed to guarantee high precision when repositioning it at a later
date. This is important to enable measurements to be performed over time without
needing to leave the instrument on-site.
The IBIS-L system offers the following advantages over currently available monitoring
systems (GPS, extensometers):
Permits the operator to perform remote monitoring of the area (remote sensing),
without the need to access the area to install sensors or optical targets;
Supplies a continuous displacement map of the entire area. The IBIS-L system
simultaneously measures all the displacements of the entire area illuminated by
the antenna beam, which can cover as much as hundreds of thousands of square
meters;
Directly measure the displacements of the territory of interest in near real time;
It can be used both day and night and in almost all weather conditions;
It doesn’t require the continuous presence of an operator and can be controlled by
wireless connection.
This possibility of also performing long distance monitoring, with no need to install
sensors means that investigations can be performed even when:
the area of interest is not accessible;
the area of interest is particularly large and therefore would require many in situ
sensors;
In addition, when the monitoring activity is required to assure people’s safety in
emergency situations, the possibility of performing remote monitoring may be essential
for protecting lives.
Fig. 2.1 shows the composition of IBIS-L system. The main components are:
o Sensor module: this generates, transmits and receives the electromagnetic signal.
The sensor module is installed on the linear scanner: movement of the sensor on
the linear scanner permits the use of the SAR technique to obtain a two
dimensional image of the scenario. This module has a USB interface for
connection with the control PC and an interface to the positioning module;
o Linear Scanner, consisting of a 2.5 metre long aluminium track, along which a
slide is moved under the control of a step by step motor;
o The control PC, installed with the system management software. This is used to
configure the acquisition parameters, manage measurements and view the results
in real time;
o Power supply: this supplies power to the system through a battery unit or
connection to an external energy supply.
A detailed description of each component is reported in paragraph 3.
