Question 720Navigation General

70% to pass

Coral atolls, or a chain of islands at right angles to the radar beam, may show as a long line rather than as individual targets due to _______________.

A the pulse length of the radar
B limitations on range resolution
C the multiple-target resolution factor
D the effects of beam width
AI Explanation

The correct answer is D) the effects of beam width. The beam width of a radar system can cause coral atolls or a chain of islands to appear as a long line rather than individual targets. This is because the radar beam covers a wider area, and the reflected signals from the closely spaced islands or atolls merge together, creating a single, elongated target on the display. The other options, such as pulse length, range resolution, and multiple-target resolution, are not the primary factors that would contribute to this effect.
