Navigation General · Radar Measurement
On radar, the most accurate measurement is generally:
- ARange, because it depends on precise timing rather than beam width✓ Correct
- BBearing, because the beam is very narrow
- CTarget identity
- DTarget color
Explanation
Radar range is measured by signal travel time and is quite accurate. Bearing is less precise because the horizontal beam width spreads the echo, so a radar fix favors range arcs and crosses ranges from two or more objects when possible.
