4GENERAL DESCRIPTION
The HYDRA system is designed to provide real time displacement
information with an accuracy of a tenth of a millimeter. The HYDRA system
is particularly suitable for a range of applications depending on the
configuration:
•Hydra G HP for Slope Monitoring: it is capable to detect and
measure both slow and fast movements in various different
environments, like for example Quarries, Open pit mines,
Landslides and Cut-slopes;
•Hydra G LP for Building Monitoring: with its all-in-one software
package, Surf Scan, it permits fast movement detection of a
Building, for example during the foundation consolidation process;
•Hydra U for Tunnel Monitoring: it aims to monitor rock fall
precursory event and provide warning in advance to evacuate
people and machinery at risk.
All the Hydra configurations operate at the same frequency.
The performance of the HYDRA system depends on the operative
measurement conditions (above all, related to the reflectivity of the area
under investigation); however, the best performance characteristics can be
defined as follows, depending on the configuration and type of antennas.

4.3 System Composition
The main components are:
▪Radar Sensor: this generates, transmits and receives the
electromagnetic signal. The Radar Sensor is installed on the Pan-Tilt;
▪Positioning Unit, made of a Pan-Tilt Unit (PTU) and a metallic arm to
hold the Radar Sensor. The movement of the Radar Sensor on the
PTU permits the utilization of an Arc-SAR technique, that obtains a
two dimensional image of the scenario;
▪Tripod unit, for the installation of PTU;
▪Power Supply Unit (PSU): supplies power to the system through the
batteries. Mains supply is used to load the batteries. Embedded in
the PSU there is the control computer, equipped with the system
management software. This is used to configure the acquisition
parameters, manage measurements and transmit data to the control
room;
▪Camera: provides a panoramic view or shots of the monitored area;
in case of HYDRA U and HYDRA G HP model it also have IR capabilities
to work during the night or in darkness.
▪IR Laser (only for HYDRA U model): installed on the PTU, act as a laser
scanner to reconstruct the surface of the monitored area, on which
are projected the radar data.
▪Cables: Hydra is supplied with 3 cables, a Main Cable connecting the
Power Supply Unit to the Pan-Tilt Unit, a Camera Ethernet Cable, and
a Power Cable connecting the PSU to the main power line.
▪Optional components: The HYDRA system can be integrated with two
optional components, a Siren Alarm and a Spotlight.
A detailed description of each component is reported in Chapter 5.

The Radar Sensor is fitted with two waveguides, each with four threaded
holes, for the installation of the pair of antennas (Fig. 5).
HYDRA antennas are protected by a Radome protective cover (Fig. 7).
5.3 Positioning Unit
The Positioning Unit (Fig. 10) consists of:
•The Pan-Tilt main body, made in aluminum and plastic, with
dimensions 32x20x21 cm and weight <10 kg, capable of moving the
Radar Sensor in azimuth and elevation;
•A Triggering Magnetic Sensor to synchronize the Pan-Tilt rotation and
the radar acquisition;
•The Arc SAR arm 50 cm long holding the payload items;
•An Elevation Pointing System that is the support of HYDRA Radar
Sensor and permits the main beam of the antenna to be orientated
in elevation towards the area to be observed.

Fig. 10 –Pan-Tilt Unit
The elevation pointing system is fixed on the Arc SAR arm through 2 cam
levers and 2 knobs. The cam levers are the rotation fulcrums of the pointing
system, while the knobs permit to select different Radar Sensor bearings,
between -30° and +30° (see Fig. 11). In Hydra-G LP configuration the
Elevation Pointing System must always be positioned at 0°; in Hydra-G HP
and Hydra U configuration the position must be the same of the Camera
tilting angle (see Par.5.7).

Fig. 12 –Screw Holes for Laser installation
On the Elevation Pointing System there are 3 fixing point to hold the sensor
in place, two of them are composed by a pull-tab, the third uses a knob (see
Fig. 7).
The PTU must be connected to the Power Supply Unit (PSU) with the Main
Cable, attached to the 32-pins connector (Fig. 13):
Fig. 13 –32-pins connector for the Main Cable
Depending on the system configuration, the function of the Positioning Unit
is different:
•For Hydra-U, the PTU is used to move the Laser in azimuth and
elevation to perform surface reconstruction and the Radar Sensor
in azimuth for the actual monitoring. During surface reconstruction
the PTU moves performing a serpentine, alternating clockwise and
counterclockwise scans in azimuth, increasing the elevation angle
at each scan. During the actual scan, instead, the PTU moves in
azimuth at a fixed elevation from -60° (the magnetic trigger angle,
see Fig. 14) to +60° clockwise, and then returns to the magnetic
trigger angle (counterclockwise).
