Question

Consider the following activities: In how many of the above activities can the radars be used?

  1. 1.

    Tracking the migration of animals

  2. 2.

    Identification of narcotics on passengers at airports or in aircraft

  3. 3.

    Monitoring of precipitation

Options

a

Only one

b

Only two

c

All three

Answer
d

None

Explanation

Radars are utilized in all three activities. Weather radars monitor precipitation. Millimeter-wave radars (used in airport body scanners) detect concealed items, including narcotics, under clothing. Specialized aero-ecological radars (like NEXRAD) are routinely used by biologists to track large-scale migrations of birds, bats, and insects.

Modern radar technology extends far beyond aviation, encompassing meteorological tracking, security scanning, and ecological monitoring.
