Notetaker: Remote Sensing Flashcards
+ Launch Vehicle
Identify
Used to put the satellite into its desired orbit
Launch Vehicle
Identify
The science and art of identifying, observing, and measuring an object without coming into direct contact with it
Remote Sensing
Identify
Provides its own source of energy
Remote Sensing Type
Active
Identify
Records/measures energy that is externally available?
Remote Sensing Type
Passive
Identify
Can be used to examine wavelengths not sufficiently provided by the sun?
Remote Sensing Type
Active
Identify
Example:
Synthetic Aperture Radar (SAR)
Remote Sensing Type
Active
Identify
- Detects external stimuli
- Records energy that is reflected or emitted
Remote Sensing Type
Passive
Identify
Examples:
* Electro-Optical Sensors
* Infrared Sensors
Remote Sensing Type
Passive
All sensor classifications have what sensors?
- Ground-based
- Space-based
Identify
Uses Passive Remote Sensing to capture, observe, and record visual EM (light) reflected and emitted by objects
Electro-Optical (Visual)
Identify
Uses Active Remote Sensing to transmit pulses, receive reflected energy back from objects, and then record the EM (microwave)
Radars (Microwave)
Identify
PIR sensors capture, observe, and record EM (IR) reflected and emitted by objects
Infrared (SWIR & MWIR)
Identify
AIR sensors combine the technology of PIR and radar to detect movement in IR
Infrared (SWIR & MWIR)
Identify
Uses both Active and Passive Remote Sensing to transmit, detect, record, and re-transmit EM (radio waves)
SATCOM (Radio Waves)
Identify
The space segment (satellite) is NOT considered Remote Sensing
PNT (Radio Waves)
