Question 1389Navigation General

The correct answer is D) Arc. When using radar to obtain a range to a small, charted object such as a navigational light, the resulting line of position will be in the form of an arc. This is because the radar signal travels in a circular pattern, and the distance between the radar and the object is measured along this circular path. The arc-shaped line of position represents the set of possible positions where the object could be located based on the measured radar range. The other answer choices are incorrect because a hyperbola, parabola, or straight line do not accurately represent the geometry of a radar range measurement to a small, charted object.
