How has the radar helped?

Answer 1

Radar is where microwaves are transmitted and received by special equipment. Objects that reflect radar can be detected by radar

Radar was initially developed to enable enemy aircraft to be detected and their position, speed and direction calculated so that defending aircraft could be scrambled to attack them. It is likely that without the advantage of radar, the Germans would have gained air superiority over Britain and launched a full scale invasion during the second world war.

More portable equipment was made that was fitted to ships and aircraft to enable enemy targets to be found at night or in times of low visibility like fog.

Today most aircraft, ships and even small yachts are fitted with radar. It can enable you to see reflective objects like other aircraft or ships, land or even areas of rain at night or in poor visibility conditions.

If you look at websites with weather information it often shows radar images that shows where heavy rain is falling or is predicted to fall.
