The task

What is the main reason the mechanism involving scan rates and side lobe-gain does not explain the subsequent movement of the blips? A. The signal characteristics do not correspond to any likely radar system. B. The same constant source could not generate rapidly moving blips and, consecutively, stationary blips for as long as 3 minutes. C. The required signal strength enhancement is improbable. D. The targets were displayed at high elevations. Return only the single uppercase letter of the correct option.
