EW
What is Electronic Warfare defined as
"any military action involving the use of electromagnetic and directed energy to control the electromagnetic spectrum or to attack the enemy."
Frequency
- Indicates size of the RADAR, which indicates possible platform.
Pulse Width
- Indicates the range of the RADAR. Determines range resolution.
PRF
-Determines RADAR precise range.
Air Search:
3-D contact location: bearing, range and elevation. (Ex. AN/SPS-48)
Fire Control
: directs missiles towards their intended targets. (Ex. AN/SPQ-9B)
Refraction
A change in direction of a wave when passing through another medium.
Doppler Effect
A change in frequency due to the speed and relative position of a contact (ex. When the siren on an ambulance seems to change tones as it approaches, passes or moves away from you).
Electronic Protection
A passive means of protecting personnel, facilities, and equipment from any effects of friendly or enemy employment of EW that degrade, neutralize, or destroy friendly combat capability. (EMCON, Spectrum Management)
Multiplexing
A process where multiple analog message signals or digital data streams are combined into one signal over a shared medium
Continuous Wave (CW)
A type of RADAR system where a known stable frequency is transmitted and then received from any reflecting objects. By taking advantage of the Doppler Effect, the RADAR is able to identify contacts while being immune to interference from large stationary objects and slow-moving clutter.
