Target Trails
The trails of the radar echoes of targets may be displayed in the form of synthetic afterglow. Target
trails are chosen either relative or true and may be sea or ground stabilized. True motion trails
require a compass signal and own ship speed input.

Trail mode
You may display echo trails in true or rel-
ative motion (only true trail on TM). Rel-
ative trails show relative movements
between targets and own ship. True
motion trails require a gyrocompass
signal and own ship speed input to
cancel out own ship's movement and
present true target movements in accor-
dance with their over-the-ground speeds
and courses.
