Answer:
(b)
Answer: B 1 Nothing of this sort is known 2 is correct: Weather radars usually work with three main types of data. In the reflectivity mode, return echoes from targets are analyzed for their intensities to establish the precipitation rate in the scanned volume. 3 is correct: Radar technology is mainly known for generating weather data and for the surveillance of aircraft. Less well known are its applications in the study of migratory birds, bats, and insects, which initially showed up as “phantom signals” on the radar screens during World War II.
