How does radar help in military?

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.

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).
