Starting a target track
During normal operation, some echoes are clearly more interesting than others. In many situations specific echoes may be regarded as targets. To set up the SU90 system to provide such information, you can start target tracking.
Context
A target track permits the SU90 system to automatically control the tilt and bearing based on the movements of the chosen target. It locks on the target defined by its position, heading and speed. The tracked target is regarded as an object, and it is identified with a circle and two lines. The two lines reflect the size of the current tracking area.
The bearing and tilt settings are automatically adjusted to follow the movements of the tracked target. The bearing line is automatically locked on the object to reflects its bearing.
Note
If you change the tilt or bearing settings manually the priority status is lost. The SU90 system will still attempt to track the target, but the tilt and bearing settings are not adjusted.
A new manually initiated tracked object is automatically given priority status. The priority is identified with a "P". Only one single object can be given priority status. If you start tracking a new target the first target will loose its priority. The same applies if you give priority to another marker. The tracking of the first target will however not stop, and the target marker is still shown.
Tip
Relevant information about the tracked object can be found in the bottom left corner of the view. If you think the text is small and hard to read, double-click on the text field. This will increase the text size.

Procedure
1 Place the cursor over the echo you wish to track.
2 Press Target Track on the Operating Panel.
or:
3 Place the cursor over the echo you wish to track.
4 Right-click to open the shortcut menu.
5 Select Initiate Track.
Further requirements
Under certain circumstances the target tracking may not follow the intended echo. This may for example happen if the tracking area is too large. You can initiate manual tracking by placing multiple markers on your target echo as it moves in the view. This location of the markers in the view will then show you the historic path of the target.
