Selecting a geographical area for accurate target tracking
When you have an echo you wish to track, the tracking functionality places a geographical
area around the object. An invisible area - the tracking area - is created as an acquisition area.
In order for the CS90 system to find and lock on the intended target, it needs to be kept within
this tracking area. If the intended target falls outside the area, the tracking can not be started.
Context
Illustration:
A
Each
Tracking Area
option controls the distance from
the inner to the outer radius of the area.
B
The width of the area is fixed, and stretches across
a predefined number of beams. This means that the
actual width depends on the distance from your vessel
to the area.
The
Tracking Area
function is used to select the physical
size of the area. You can choose from a set of predefined
sizes.
To track a target efficiently, the area should be as small as
possible. For example, use a small area if you track single
fish or small schools. However, if the target is large, or
moves very fast, a larger area may be beneficial. This may
be useful if you track a large school of fish.
Tip
Under certain circumstances the target tracking may not
follow the intended echo. This may for example happen
if the tracking area is too large.
Procedure
1
Open the
Setup
menu.
