RADAR (an acronym for RAdio Detection And Ranging) is a sensor system that uses electromagnetic rays to detect objects, identify them, and determine their velocity. RADAR was first introduced during the Second World War.
RADAR can operate in an active mode, generating pulses of radio waves, receiving echoes reflected from objects they strike, and analyzing the echoes to determine the characteristics of the objects that reflected the initial pulses.
RADAR can also operate in a passive mode, simply receiving radio waves from other sources and analyzing them.
Development
The first used of RADAR was on a large scale requiring massive antennas and the units were largely just an array of large antennas and receivers that were only able to detect targets from only certain directions. Later systems made use of rotating transceivers that allowed for a station to scan potentially from any direction. With the invention of the magnatron microwave generator, RADAR began to be able to mounted on aircraft to further improve detection methods and RADAR's defensive capabilities. It was during WWII that we saw the greatest advances in RADAR tech as both the Allies and the Axis worked to find ways to detect, jam, intercept, penetrate and destroy their enemy's RADAR defense networks. RADAR mounted on combat aircraft and ground installations are required to target and destroy targets with RADAR guided long range anti-aircraft missiles.
When mounted on combat aircraft they allow for the pilots of the those aircraft to target and engage enemy aircraft in night time conditions. Initially this was restricted to specifically designed Night Fighters that had the space available for the large RADAR units. As RADAR systems were improved and miniaturized More and more aircraft gained this capability until today there isn't combat aircraft that does not have this capability.
