The radar equipment should assist in safe navigation and
in avoiding collision by providing an indication, in relation to own
ship, of the position of other surface craft, obstructions and hazards,
navigation objects and shorelines.
For this purpose, radar should provide the integration and display
of radar video, target tracking information, positional data derived
from own ship's position (EPFS) and geo referenced data. The integration
and display of AIS information should be provided to complement radar.
The capability of displaying selected parts of Electronic Navigation
Charts and other vector chart information may be provided to aid navigation
and for position monitoring.
The radar, combined with
other sensor or reported information (e.g. AIS), should improve the
safety of navigation by assisting in the efficient navigation of ships
and protection of the environment by satisfying the following functional
requirements:
- in coastal navigation and harbour approaches, by giving a clear
indication of land and other fixed hazards;
- as a means to provide an enhanced traffic image and improved situation
awareness;
- in a ship-to-ship mode for aiding collision avoidance of both
detected and reported hazards;
- in the detection of small floating and fixed hazards, for collision
avoidance and the safety of own ship; and
- in the detection of floating and fixed aids to navigation (see Table 1, note 3).
