weather radar is a great help to pilots in detecting thunderstorms. however, pilots must be aware that radar does not reliably detect hail. radar operates by transmitting a pulse of radio energy and receiving the pulse again after it is reflected by a target. large raindrops, the kind found in intense thunderstorms, are the best radar reflectors and will show up as intense targets on the screen. hail is somewhat porous and has an uneven structure; it tends to absorb or scatter the radar pulse rather than reflect it back to the antenna. according to the paragraph, weather radar does not reliably. detect hail because of
its penetrable surface
