Target Analyzer - Suzuki SMD16 Operator's Manual

[Rough]: Suitable in rough weather conditions where sea clutter is strong. Applies high
sea clutter reduction. Weak bird echoes may be suppressed in this setting.
To select the bird mode setting, tap the display to open the pop-up. Select [Bird
Mode] and desired setting option, [Calm], [Moderate], [Rough], or [Off].
Usage precautions
• Bird mode is available with radar sensors FURUNO DRS2D/4D/4A/6A/12A/25A,
software version 01.18 or after. Bird mode is also available with the X-Class radar
sensors (FURUNO DRS6A X-Class, DRS12A X-Class, DRS25A X-Class) and the
solid-state radars FURUNO DRS4D-NXT/6A-NXT. The radar sensors FURUNO
DRS4DL/DRS4DL+ do not support Bird mode.
• Do not use the Bird mode in rough weather.
• Do not use the Bird mode during a voyage. The Bird mode settings are not suitable
in a voyage.
• ARPA performance may be reduced when the Bird mode is active.
• Radar Adjust (Gain, Sea, Rain) and Auto Sea Mode cannot be adjusted when the
Bird mode is active.
• Schools of fish that attract birds tend to dive suddenly, which may result in unstable
or disappearing echoes.

Target Analyzer

The target analyzer paints radar echoes in the colors shown in the illustration and ta-
ble on the next page, to help you distinguish targets that are moving and getting close
to own ship. Requires the radar sensor FURUNO DRS4D-NXT/DRS6A-NXT and GPS
position data. Radar Adjust (Gain, Sea, Rain) and Auto Sea Mode cannot be adjusted
when the Target Analyzer is active.
Note: When the radial component of target velocity (see below for description) is 50
kn or higher, the target may be painted in a wrong color. For example, an approaching
target whose speed is 50 kn or higher should be painted in red, but is painted in green.
Radial component of target velocity: The target velocity can be separated into two
components, the radial and transverse components, as in the figure below. The radar
