Suppose the desired angle were 45°. Then a change of 6° is enough to throw the reading off by 10%.Agreed radar is not accurate to laboratory standards, but 10% sounds like a high number. If the nominal angle is 45 degrees, then the target is as far away as the radar unit is high, i.e. about 3 feet. I can't imagine that vertical curvature would have much of an effect over such a short horizontal distance...extreme VC radii are on the order of 500'. |
