focused into a single beam by the radar antenna, a small amount energy is transmitted in
other directions. This energy is referred to as sidelobe energy and occurs in all radar systems.
The returns caused by sidelobes tend to appear as arcs.
Ú
Note:
This control should only be adjusted by experienced radar users. Target loss in
harbor environments may occur if this control is not adjusted correctly.
When the radar is mounted where there are metallic objects near the radar, sidelobe energy
increases because the beam focus is degraded. The increased sidelobe returns can be
eliminated using the Sidelobe Suppression control.
By default, this control is set to Auto and normally should not need to be adjusted. However,
if there is significant metallic clutter around the radar, sidelobe suppression may need to be
increased. The control should be adjusted as follows:
1.
Set Radar range to between 1/2 nm to 1 nm and Sidelobe Suppression to Auto
2.
Take the vessel to a location where sidelobe returns are likely to be seen. Typically, this
would be near a large ship, container port, or metal bridge.
3.
Traverse the area until the strongest sidelobe returns are seen.
4.
Change Auto sidelobe suppression to OFF then select and adjust the sidelobe
suppression control until the sidelobe returns are just eliminated. You may need to
monitor 5-10 radar sweeps to be sure they have been eliminated.
5.
Traverse the area again and readjust if sidelobes returns still occur.
6.
Exit the dialog.
Radar sector blanking (Halo radar only)
Radar installed in close proximity to a mast or structure could cause unwanted reflections or
interference to appear on the radar image. Use the sector blanking feature to stop the radar
from transmitting on up to four sectors in the image. The blanking occurs on the main radar
PPI and on the radar overlay on a chart.
Ú
Note:
Sectors are setup relative to the heading line of the radar. The bearing of the
sector is measured from the center line of the sector.
Ú
Note:
Sector blanking should be applied very carefully to avoid reducing the radar’s
usefulness in identifying valid and potentially dangerous targets.
Main radar PPI Radar overlay on a chart
Adjust open array park angle (Halo Radar only)
The park angle is the final resting position of the antenna relative to the heading line of the
radar when the radar is set to standby. The antenna will stop rotating at the desired offset.
Halo light
Controls the levels of the Halo Radar pedestal blue accent lighting. There are four levels
possible for the lighting. The accent lighting can only be adjusted when the radar is in
standby mode.
Ú
Note:
The blue accent pedestal lighting might not be approved for use in your boating
location. Check your local boating regulations before turning the blue accent lights ON.
