target bearing has nothing to do with north south east or west, it is the bearing in degrees off your bow. your bow is 0, your stern is 180, always, regardless what direction you are traveling.
so
"contact bearing 270" would be at 9 o clock if you were facing 0 (your bow)
the only time a sailor will tell you what direction the target is heading, is when you take 2 range readings in the perescope, and have them estimate their speed as i described above.
to summerize:
bearing= degrees off your bow
heading= direction in degrees target is traveling (0 is north, 90 is east, 180 south, 270 west)
the easiest way to look at an exact bearing is to go to the perescope or binoculars and look at the numbers at the top, they will change as you move the mouse left or right.
