Radar Observer · Plotting — Vectors
In the standard radar plotting triangle, the line labeled 'WO' (the we-oh / own-ship vector) represents:
- AThe target's true course and speed
- BOwn ship's course and speed over the plotting interval✓ Correct
- CThe relative motion line
- DThe closest point of approach
Explanation
In the OAW/relative-plot triangle, W-O is own ship's true motion vector, O-A is the relative motion of the target, and W-A is the target's true course and speed. Combining them yields CPA, TCPA, and the target's true track.
