Question

which cause radar waces​

Answer 1

Answer:

The decrease in density of the Earth's atmosphere with increasing altitude causes radar waves to bend as they propagate through the atmosphere. This usually increases the detection range at low angles to a slight extent. ... This results in the formation of what are called radar holes in the coverage.

Hope it helps you...

Answer 2

THE DECREASE IN DENSITY OF THE EARTH'S ATMOSPHERE WITH INCREASING ALTITUDE CAUSES RADAR WAVES TO BEND AS THEY PROPAGATE THROUGH THE ATMOSPHERE. THIS USUALLY INCREASES THE DETECTION RANGE AT LOW ANGLES TO A SLIGHT EXTENT. ... THIS RESULTS IN THE FORMATION OF WHAT ARE CALLED RADAR HOLES IN THE COVERAGE.
