Radar
Part used to transmit and receive the electromagnetic energy.
Includes laser and RF pulsars. These tend to be highly directional weapons that emit RF over a narrow band of frequencies.
What are Directed Energy Weapons(DEW)
Loss of amplitude through a process known as attenuation.
What is Damping?
A branch of science that deals with the measurement of the intensity of visible light relative to perceived brightness to the human eye.
What is Photometry?
3 dimensional representations of transmitted EM energy
What are Beam Patterns?
Provides a heartbeat for the radar telling the duplexer when to switch between transmit and receive modes.
What is Synchronizer(Timer)?
When hot materials become luminous and radiate light.
What is Incandescence?
Boundary between two media
What is Discontinuities?
Science of measuring light in any portion of the electromagnetic spectrum in terms of absolute power radiated by the source.
What is Radiometry?
Horizontal slice used to cover a greater area. Primarily with radars that scan large portions of the sky as they search for targets.
What is Horizontal Fan Beam
Any display of information after a computer has eliminated noise and created a symbol for each target.
What is Synthetic(video)?
Caused by NUDETs and create tremendous amount of RF.
What is EMP
Three parts of Electroptical Range.
What is Infrared, visible and ultraviolet.
Daily Double
Filter that will only pass wavelengths or frequencies of light within a specified range.
What is Band Pass?
Vertical slice used to cover a greater area. Primarily with radars that scan large portions of the sky as they search for targets.
Vertical Fan Beam?
Radar that uses the same antenna to both transmit and receive the electromagnetic energy.
What is Mono-Static Radar?
Daily Double
Three RF sources of military interest.
What is nuclear detonations, directed energy weapons, and radar?
Antenna that radiates in all directions
What is Omni directional Antenna?
Disperses light through various methods including gratings and dispersion prisms.
What is Spectrometer?
Used by pencil beams is stepped in elevation after each horizontal sweep.
What is Raster scan?
Oscilloscopes that display the detected and amplified target return signal.
What is Raw Display?
Emission of light by certain materials when they are relatively cool.
What is luminescence
Data buss that transmits one direction at a time
What is Simplex?
Special prisms with very high indices of refraction that cause light to rapidly disperse.
What is Dispersion Prism.
Vertical fan beams used commonly by search radars that continuously rotate the beam through 360 at a constant rate.
What is Circular Scans?
