How does radar help in military?

Instrumentation Radars These tracking radars function as a measuring device on military ranges and test facilities. They are employed by the military to measure metric performance data on aircraft, projectiles, missiles, and satellites .

Long-range surveillance radar uses HF, UHF, VHF, and L-band frequencies to detect targets out to 2,000 miles or more . How can it see that far when the curvature of the earth limits our line of sight to about 15 miles? Two ways: ground wave propagation (GWP) and over-the-horizon radar (OTH).

Radar, which is essentially “seeing” with radio waves, found dozens of other uses in the war. It was used to aim searchlights, then to aim anti-aircraft guns . It was put on ships, where it was used to navigate at night and through fog, to locate enemy ships and aircraft, and to direct gunfire.
