Use modes

Note:
Radar User modes are only available for Halo radar antennas.
Use modes are available with preset control settings for different environments. The
following modes are available:
• Custom - In this mode all radar controls can be adjusted and will be retained after a mode
change or radar power cycle. Radar defaults are set for general purpose use.
• Harbor - In this mode the radar settings are optimized for areas such as busy waterways
and large man-made structures where good target discrimination and rapid image
updates are needed.
• Offshore - In this mode the radar settings are optimized for offshore sea conditions and
making isolated targets larger and easy to see.
• Weather - In this mode the radar settings are optimized for best detection and
presentation of rain clutter. Image update rate is slowed and color depth is increased.
• Bird - In this mode the radar settings are optimized for best detection of birds. The radar is
set up for maximum sensitivity. This mode is not recommended for use in congested
harbor environments.
Not all controls are adjustable in each mode. The following table shows preset controls and
adjustability for each control.

* Maximum range is dependent on antenna length: 3' = 48 nm, 4' = 64 nm and 6' = 72 nm.
Radar threshold
The threshold sets required signal strength for the lowest radar signals. Radar returns below
this limit are filtered and are not displayed.
Default value: 30%.
Rejecting radar interference
Interference could be caused by radar signals from other radar units operating in the same
frequency band.
A high setting reduces the interference from other radars.
In order not to miss weak targets, the interference rejection should be set to low when no
interference exists.
