Choosing the colours used to present the echoes
Several different colour scales are predefined and available for the presentation of the
echoes. You can easily choose which colours to use. The presentation colours have no effect
on the operational performance of the ST90 system.
Context
Which colour scale to use is mainly a personal preference based on ambient light conditions,
the nature of the echoes and your own experience. Keep in mind that in the basic scale
with 12 colours, each discrete colour represents a 3 dB range of echo signal strength. This
implies that the next colour is selected every time the echo strength is doubled. If you
choose to use many colours, the resolution of the display presentation is greatly improved.
It is then easier to distinguish the difference between the various echoes of different size
and/or target strength.
