CA34/44/54 Radar menu Chapter 3-1
3. Radar operation
The CAXX combines chart plotting with radar navigation. For first
time users of Radar, we have included a basic description of the
radar presentation with a basic understanding of how the controls
affect the radar’s operation and display.
The following paragraphs describe the control settings used for
initial display setup, turn-on procedure, inclement weather operation
and finally the turn off procedure. Radar controls are described in
chapter 3.2.
3.1 Radar picture
The radar picture appearing on the display is a map-like representa-
tion of the area in which the radar is operating. Typically, the ship’s
position is at the center of the display. The operator may reposition
or offset the ship’s position up to 66% of the radius anywhere on the
screen. The ship’s dead ahead bearing is indicated by the heading
line at the 0° relative bearing.
Coastline contours and landmass are generally depicted in solid
filled yellow, purple, multi-colored (DAY settings) or green (NIGHT
settings) echo areas - choose colors in Pallette setup, section 9.7.
Other surface vessels, and channel buoys, are displayed as smaller
single “blips” or echoes. The radar picture or map can be viewed in
many different ranges from own ship. These sizes are selected by
the range controls. Greater detail of radar echoes nearby own ship is
shown when the short or nearby range scales are selected. The best
technique for assessing the radar presentation characteristics is to
start with using a longer range scale and then switching to shorter
ranges when nearby targets appear, or as the ship approaches the
coastline, harbor, or other vessels in the area.
The long range scales (i.e. 3, 6, 12, 24nm) best show the overview of
the ship’s relationship to landmasses, weather fronts, and large ship
targets at or beyond view.
