Radar Fundamentals Flashcards
What does RADAR stand for?
Radio Detection and Ranging
Identify
- Detects and tracks moving objects
- Operate day or night
- Operate in almost all weathers
- Has very broad coverage
Radar
Identify
30 MHz - 2 GHz
Radar Frequency Ranges and Applications
Search Radars
Identify
1 GHz - 8 GHz
Radar Frequency Ranges and Applications
Search & Track Radars
Identify
4 GHz - 18 GHz
Radar Frequency Ranges and Applications
Fire Control & Imaging Radars
Identify
8 GHz - 100+ GHz
Radar Frequency Ranges and Applications
Missile Seekers
Identify
- Transmitted Pulse
- Propagation
- Reflected Pulse “echo”
- Echo is recorded and output to a display
Principles of Operation
Identify
Amount of the radar signal intercepted or redirected back toward the radar
RADAR Cross-Section (RCS)
Identify
Measures how effective the target is in reflecting the radar signal
Target (RCS)
- Size
- Shape
- Orientation
- Composition
What does TEARR stand for?
- Time
- Elevation
- Azimuth
- Range
- Range-Rate
Identify
When a radar measurement is made and recorded
TEARR
Time
Identify
- Vertical Direction determination
- Measured from the horizontal plane
TEARR
Elevation
Describe Elevation and Azimuth Resolution
The farther the satellite, the better the resolution
Identify
- Horizontal Direction determination
- Measured from North
TEARR
Azimuth
Identify
The distance between the radar and the target
TEARR
Range
