ANGLE OF REFLECTION
The angle between the reflected wave and the normal .
ANGLE OF REFRACTION
The angle between the normal and the path of a wave through the second
The unit used to define the wavelength of light waves .
The property of a radiator that allows it to emit strong radiation in one direction .
A conductor or set of conductors used to radiate RF energy into space or to collect RF energy from space or to do both .
ANTENNA BEAM WIDTH
Width of a radar beam measured between half-power points .
A device used for impedance matching between an antenna and a transmitter or receiver .
Routes RF energy from the transmitter, radiates the energy into space, receives
echoes, and routes the echoes to the receiver .
An electronic circuit used to minimize the effects of enemy countermeasures, thereby permitting radar echoes to be visible on the indicator .
