Target Analyzer (Non-IMO only)

The target analyzer function analyzes echoes and assists the operator to determine
dangerous targets. This function is particularly useful under heavy rain/snow or where
there is surface reflection, which can cause interference and noise.
The target analyzer function can also place hatching over heavy rain areas, reducing
the visible interference and allowing a clearer view of potential targets.
Echoes are displayed in five different colors to assist the operator in identifying tar-
gets. The colors and their respective echoes change depending on the echo color se-
lected from the [BRILL] menu (see section 1.43.2) are shown in the table below.
