Manufacture
The Radar Integrator Board enables
- Automatic detection,
- Automatic acquisition and automatic tracking of targets
- Calculations of the targets coordinates and motion parameters, and
on-line transmission of this data to the systems
the formation of a radar picture to be displayed together with an
electronic chart.

Compatibility
RIB is a hardware module fully compatible with
Navi-Sailor
and Navi-Harbor
systems, intended for the reception of an analog video signal from the
radar and its digital processing.
Functionality
Combination of a chart, current coordinates and the surface
situation data allows the instant assessment (at a single glance) of the
sailing conditions relative to the surface dangers shown by the radar,
and submerged obstacles displayed on the chart.The general-purpose
channels designed for synchronization and interface with radar, as well
as programmable devices for communication with logs and gyros, ensure
the RIB interfaces with any type of navigation radar. The long term
capability to record the radar picture and tracked targets motion and to
play back this recording at a later date, ensures accurate documenting
of the navigational situation.

Integrator Board/ Hardware components
|
The Radar Integrator consists of
a short (120 mm) PCI standard board installed in the computer and
two external modules: a high frequency module (HF-box) and a low frequency
module (LF-box), connected with a PCI board with cables. HF-box has two BNC
connectors for input signals, whilst the external lines are connected to the
LF-box by means of screw terminals. |
