Relative Motion (R) with TRAILS

A ship in motion in the same speed and heading (e.g. shipping lane) is displayed
with no afterglow in the radar video.

Relative trails is the original radar method to view plot history (also with EBL) to
quickly see which approach own ship. In Figure: 2

−

20 the other ships are all

heading west (ARPA data). Relative Trails / BCR information is an option for
experienced radar operators.
